The voltage coming of the transformer is nominally somewhere like 18v. To get it down to 12v all the current is put through the 33ohm resistor which has the 12 zener tied between the other side and ground. The 12v supply (drawn from memory) is: (excuse the poor ascii graphics.) 18v--\/\/\/\/\--12v-- | 33ohm | | ¬ === /\ 12v zener | 4700uF -- | | -0v-- So under no load there is a drop of 6V across the 33ohm resistor which gives a current of 0.18A which is just over 1W to be dissipated as heat. This also means the zener has to lose over 2W of heat as well. As the load from sam increases, by running two disk drives for example, more of the current goes through sam and takes the load off the zener but the resistor still has to burn off the excess voltage. The problem with this type of regulation is the resistor has to have a small enough resistance to let enough current through under max load conditions and heavy enough to dissipate the heat. If you're not using all of the 0.18A available, e.g. you only have one floppy drive, then you can increase the 33ohm resistor which will still drop the excess volts but draw a smaller current, and so be cooler. These days, of course, a 7812 would more than likely be cheaper than a big resistor :-) Nev
Re: Power supply circuit diagram
I made a few photos of my PSU: http://www.keprt.cz/sampsu1.jpg http://www.keprt.cz/sampsu2.jpg You can clearly see that D4 is missing (right-bottom), and there is a very large old zener diode put there instead. It is Tesla 6NZ70 - 12V 1.5W Zener diode which proudes a LOT of heat. (If I count correctly, a 2.5W diode should be used instead.) I am also suspicious about R1 (large grey resistor right beside D4) which is a bit mechanically damaged (clearly visible on the second photo), and also C4 (one of the large capacitors) which seems to me a bit bloated. So do you recommend me to put there 1N5349 instead of that old big boy? (Local retail shop here offers me 1N5349, not 1N5349B, but I think it is the same and maybe it actually is the B version.) I don't use my Sam often, I just nostalgically keep it. So I don't want a whole new PSU.

I am also suspicious about R1 (large grey resistor right beside D4) which is a bit mechanically damaged (clearly visible on the second photo), I would recommend replacing R1 - 33ohm if I remember correctly. I use a 10W part for this - as I've repaired quite a few power supplies where the normal wirewound resistor has charred the PSU and melted the inside of the power supply case when the 12V line fails. and also C4 (one of the large capacitors) which seems to me a bit bloated. With these power supplies being made around 1984 (going by date codes I've seen on the transformers inside them) replacing the electrolytic capacitors is a very good idea.

Power supply circuit diagram
Hi guys, does anybody have the original Sam Coupe power supply unit circuit diagram? My power supply was damaged years ago and somebody repaired it by replacing something inside with an old big zener diode. I just remember that 12V line was dead and that diode is just a random one which we were able to get. Then in 90's it was not easy to buy good new diodes here, but it is easy to buy anything on internet now. So I just need to know what was the original piece in the PSU and I am going to replace it back. Thanks in advance. Aley Keprt

Re: Kaleidoscope
This is really interesting, as I ever wondered what exactly is it. (Whatever is it, they never tell you what really is it when they try to sell...) Thank you for this nice description. /--- Aley in your last email you said the Kaleidoscope was a bodge - is this coz there was no software for it? Does the Kaleidoscope realy give the Sam 32,768 true colours? I'm interested in what it is and what it does - (you never seem to hear anything about it...) It was a complete bodge. What the kaleidoscope did was pull down the RGB video signals generated by the Sam as normal (by darkening the output by varying amounts of red, green, blue - set with an OUT command to the kaleidoscope port) so it technically produced 256 tinted shades of the original colours - in total 32768 shades, but could they be used in a proper fashion - nope! So whatever value of shading the kaleidoscope was set to would affect all the colours on screen. There was no real way to use it all, could you have individually shaded pixels - nope again! At most, you could write code to tint horizontal groups of 16 pixels at a time... but for all 192 scanlines you would be using all the CPU time and even effectively tinting 16 pixel blocks that wouldn't really let you achieve any decent graphical effects, plus 62% of all the CPU time is being used. In all, a waste of time, it couldnt be utilised in any useable way at all, therefore no software attempted to used it.

Mouse emulation problems [Fw: SAM COUPE]
I forward you a translation of message from velesoft (original message is written in Czech, se below): - I checked out your Sam Coupe emulator. I tested mouse emulation and I obtained these results: All versions of the emulator(s) too early reset mouse. I borrowed the original mouse interface from Kapsa club. For example, the game Legend of Eshan, which relies on the longer delay before mouse reset, doesn't work. In this game, when it is reading the last byte of X coordinate, the emulator is actually returning the state of the keyboard, because the mouse was reset too early. When using the original Sam mouse interface, this game works correctly. The time of mouse port activity must be longer at least twice (in the emulator). Since I don't understand the mouse at all, I replied this: - Please send me that game, and I will give it to somebody who can try to fix the emulation. I personally think that the problem might be in the Sam mouse interface from Kapsa, which is probably not identical to the original interface. But it must be checked out... And that person sent me that game, and replied: - The program is correct, it only has a longer delay in mouse port reading routines and before it reads all the numbers, the emulator is returning the keyboard status again. In this game you need to hold shift key down in order to let the mouse work [in Sim Coupe - all versions]. The mouse interface is original from Samco/Samtek. You can find the schema on my www pages, it's 100% identical to the original one. (On the other hand, the schema listed in Sam tech.manual is wrong - the pin out is incorrect and C1 is missing in there.) There is no other mouse interface for Sam, just the original one. Mr. Richard Haramule tried to make a simplier solution, but he didn't finished it successfully. My new sam mouse turbo has 100% identical timing to the original interface. I wrote a test program in assembler and it showed that emulator resets the mouse ports too early. The mentioned www page is: www.velesoft.wz.cz I just wonder why this person calles all his work turbo something - it sounds to me like something really stupid, like magnificent abc...

Petehad two games released back in 1996 and 1997 - Conquest and Mage Fire, whichwere published to a limited extent by Zedd-Soft (run by Michael Stocks /Zodiac Magazine). I was also involved with the two titles way back then byadding support for the Quazar Surround soundcard to both of the games.I had previously secured permission from Pete to use Conquest and Mage Fireon the Sam Revival coverdisks (and you'll find Mage Fire on the coverdiskwith Sam Revival 12) but now with owning the titles I can go further withthem and I am already planning a revamp of Conquest to update all thegraphics and sounds. What I have to do now is go through a massive pile ofdisks to look at all the unreleased games. Expect more news soon!Gremlin Graphics Games--I have received permission from Andy Davis of Alchemist Research to use oldGremlin Graphics games on th e Sam. Now instead of just adapting the ZXSpectrum versions to run on the Sam under emulation (as was done on the oldBlitz diskzine back in the late 1990's) it is my aim to create full Samversions of some of the classic games for inclusion on the Sam Revivalcoverdisks.The first game I am looking at is 'Thing on a Spring', originally releasedback in 1984 for the Commodore 64 and Amstrad CPC only. Thing on a Spring isa bouncy and fast platformer and with some carefully planned scroll routinesit should make the transition to the Sam with few problems.Now the music for any game is very important for me, and I am planning tofeature the original SID based music (for use with the SID interface) aswell as a new rendition of the tune for the normal Sam SAA1099 soundchip. I'm pleased to say that initial work on the game remake is underway, and theSAA1099 version of the music is already complete! The SAA1099 music trackwas carefu lly composed by David Suzuki-Sanders (who also composed the 'Aboutas SID as its going to get' SAA1099 track on the audio CD with the lastissue of Sam Revival.)The second game I am looking at converting is 'Harlequin', one of the firstgames I ever played on an Amiga, and one that immediately impressed me withits graphics, music and playability. Harlequin is another scrolling platformgame, based in a fantasy dreamworld with very colourful graphics and athumping soundtrack, and was released only for the 16 bit machines in 1992 -the Atari ST and the Amiga.So why should the Sam be left out of such a great game? No reason I think!So far I have converted over the graphics for the first level from the AtariST (easier to capture via an emulator than the Amiga version), and for themain scenery and characters only 12 colours were used so this conversion wasquite straight forward.

How to erase sectors?
In order to archive=upload to NVG some of my lovely text editors which are still missing there, I need to erase the private text files I have on them. But how to do it? - If I just erase the files, the private data actually still reside on the disk and anybody can udelete and read my private stuff - There are MasterDos (sub)directories, and many hidden files, which in together makes quite unpossible to copy the disk to an empty disk, since all disk copiers I have either don't fully support subdirectories, and/or have problems with hidden files. - There are more than 80 file slots in directory structure So I assume the best idea is to have a program which scans directory structure for unused sectors and fills them with zeros (including directory entries of erased files).

Re: Ideas for the ultimate emulator :)
A game console doesn't emulate anything. It's a commercial product on its own. There are other news groups devoted to emulation and hardware emulation, and this discussion will DEFINITELY craete a huge amount of discussion not connected in any way to Sam Coupe. But Sim Coupe itself is a Sam Coupe clone, so I can hardly see any (even a very small) reason of not including it here. Sam or Sim... that's pretty the same if you can see the merit.

Re: Re[2]: Text conversion
You can use any "printer". Just install itwith file as output port (instead of LPT), and you get the text file from Sim Coupe. At least my Windows does it this way. Then it asks me each time where to save this file (surely not windows system32 directory). ASCD emulator writes everything directly to file, not using any kind of Windows printer "drivers".

Paolo, as I wrote, STI converts text files from Sam to PC. Not vice versa. In simple words: Only Sam --- PC. Bytes 10 and 13 are not present in Tasword, what is the default input encoding. So that's why STI writes those error messages. Also, I have to add one IMPORTANT note: SAM BASIC USES SPECIAL FILE FORMAT, NOT JUST TEXT FILES!!! If you want to write Basic program, use the Sam Basic. You can't write it in a text file!!! That will never work without a special Basic simulator/converter. Original Sam Basic uses format similar to ZX Spectrum basic, including all numbers in binary format, line numbers in binary format, tokenized commands/keywords (i.e. single byte per keyword), and variables stored in binary form with the Basic program in a single file. -- Mgr.(MSc.)

RE: Fastest memory transfer (on Sam)
Thanks! I did some tests on my own, and the profiling says that the most slowest part is the text scroller. I already tried many LDI's and PUSH/POP system on my own, but unfortunately the process of changing SP makes PUSH/POP slower than sequence of LDI's. You know, the TASM doesn't support clever macro's so I can simply use REPEAT statement to compute LD SP,nn for each cycle of PUSH/POP. When using dynamic scheme, i.e. LD HL,16; ADD HL,SP; LD SP,HL; it's way too slow. Push 16T and POP 12T? I believe what you say, but that Z80 timings document which I got from somebody here (last week) says PUSH 11T and POP 12T. So what's the reason of these differences? I assume that's something with memory contention on Sam, and probably all those Z80 instruction timings documents are pretty useless on Sam. Btw. Those assembler compilers I got from Sam users are not very good. If I understand it correctly, PYZ don't use ascii files. So I use TASM, but it uses nonstandard syntax (I hate it!), so I had to rewrite the original Comet source file (Comet uses quite good syntax - I think it's Zilog Z80 standard). Also, I extremely miss REPEAT and preprocessor variables, like Borland's TASM or Microsoft's MASM has on i8086 CPUs. Having the clever macros, it would be easy to write optimized memory copying code. (That stupid Z80 crossassembler TASM even can't include a binary file.) I would like to write something like: COUNTER = 16 REPEAT lines*128 LD SP,16 POP ...

Sam memory contention - I am totally confused
A SimCoupe source code comment says: // if we are in the main screen area, or one of the extra MODE 1 contended areas: // CPU can only access memory 1 out of every 8 T-States // else // CPU can only access memory 1 out of every 4 T-States Let's assume we are executing while in ray is in screen mode 4 (paper area). For example LD (HL),N is 2 bytes long and writes 1 byte to memory. So it has 3 memory accesses in total, what gives the total execution time of 24T when screen is drawn. Note that classic Z80 specs. says 10T for this instruction. So it's a quite big difference. Also, Edwin Blink wrote that for sprite drawing I should use the sequence of LD (HL),nn INC L which is 16 T per byte - but how can it be 16T in total when each memory access takes 8T? Or do I understand it wrongly? Please tell me... :-) /--- Aley
And what about ZX Spectrum memory contention - just to compare with Sam
I know this is not Spectrum users, but I must ask: how does Spectrum memory contention work? How is it possible to run Spectrum software on Sam, when it [Spectrum] definitely uses very different memory contention scheme?

Development tools wanted
Hello everybody! After 11 years I decided to refresh one of my unfinished projects, which was just about to be completed when I got my PC 486. :-) I found both literature and software in my archive, but I'd like to get some better software if there is one. I write this e-mail to ask for help. I still use the original orange ZX Spectrum manual as a Z80 instructions reference. I originally used Comet 1.4 for programming, I liked it much. I found both dikette and manual, so I can use it atill, but maybe there is a newer (and free) version, or preferably something yet better - I think that a cross-assembler for PC could be better for me. (But I need to convert the Comet source to it somehow.) Any advices? And, finally, E-Tracker. I have original version. Is there any new version, or possibly a new player routine (some bugfixes?). The original player routine works perfectly for me. I don't know wether there were more versions, or any known bugs in there. I just wonder why does it read from memory addresses around 0 - I tested it yesterday in ZX Spin debugger and SamPlay SAA player, and found that E-Tracker player reads memory at addresses around zero. Does anybody know, what does it mean? Some kind of random numbers? This is important also for my SAA player SamPlay for PC, because it doesn't contain ROM, and if E-Tracker needs ROM there, it probably doesn't play 100% as on original Sam. Any experiance? /--- Aley

Re: Spectrum on Sam games at NVG
Eh, we discussed this a week ago. :-) At first it obvious that any standard 48k games which don't need any changes to run on Sam should be removed. I don't understand why these games are at NVG in sam-coupe directory. But I think that 128k, AY and tape-disk converted games should stay. Better said, these title don't seem to be present at NVG, so we can upload them. And finally, I must add that Sam Coupe is a Spectrum clone. You can't shut your eyes and don't see this fact. 99% of good games on Sam are Spectrum games. I personally never spend much time playing that crappy Defenders, Sam Strikes Out or void Sphera. Instead, I converted Spectrum Sim City to save games to samdisk and built my cities, did great battles in 128k North and South, shoot'em all in Exolon, did assaults in 128k Laser Squad Remix, etc. I mean that any Spectrum emulation related stuff, including games should be there, except those ones that can be used in original form. For me, 90% of Sam Coupe is just a bit too expensive pseudo 128k Spectrum with a disk drive and pseudo-AY. Of course, we don't want to waste all the disk space with Spectrum stuff, so we omit all the titles which originally didn't load due to a protected loaders failed to work on a Sam's different CPU speed, if these titles can be run from a 48k SNAP file like .Z80, .SNA or .MUL. -- Mgr.(MSc.)

Re: Spectrum on Sam games at NVG
But I think that 128k, AY and tape-disk converted games should stay. They have always been a part of the SAM scene, so it does feel like they belong in the archive. I'd still be tempted to keep them in a different category from native SAM software, to make sure people are aware they're still conversions. Definitely.

Re: Fuxoft [Re: Still no tapes received]
Alright, some tunes were programmed by Fuxoft, but not composed by him. I am sure he wrote all credits to Jarre, Hubbard and others in the rolling text which was deliberately removed by Sinclair User... AFAIK those times it was absolutely normal to convert real music to Spectrum (or Amiga, mainly Amiga...). As I remember, Fuxoft wrote in his demos that he simply loves Hubbard's tunes and they are the best ever made on any computer. (I personally don't share this opinion, but it isn't important.)

(L) is Ghostbusters by Adam Bellin (and Ray Parker Jr.), M is Axel F (not sure which game), N is from the Neverending Story or Starwars or something, O is another Jean Michel Jarre one (Equinoxe?), T is a Genesis tune (Land of Confusion), U is another Jean Michel Jarre tune, V is from a James Bond game, X is another C64 game tune, Y is from an Indiana Jones game, and Z is yet ANOTHER Jean Michel Jarre tune. Since SU 111 is dated may 1991, I see no reason why they didn't contacted the author. It was 18 months after eastern block collapsed, so there were no political problems when trying to contact anybody anywhere in the east. It looks like it was rewritten by the guy who did their game cheats, so they'd trust what he said. Si

Re: Still no tapes received
Well, I tested your tapes. Good tapes, thank you very much. All of them works in ASCD when converted from TZX to TAP. I am quite happy for this, since some of them are quite nonstandard. I mean those TZX contain some garbage, which is movet do TAP as well. But ASCD proved to take only what Sam needs from those tapes. :-) I will support add TZX later. Currently I have combined TZX/TAP loader finished, just need some time to incorporate it into ASCD, since the current source code is Win32 only and the release version ASCD 0.96 is DOS only.

Re: Still no tapes received
Here is a description of what Fuxoft means. I cite Frantise Fuka: First of all, I am from the Czech Republic and Frantisek Fuka is my real name. To be more precise, there is a weird thing above the letter s that cannot be reproduced in ASCII. The whole name sounds somehow like Fran-tjee-shek Foo-kah (the Foo is short). Fuxoft is my nickname which I invented when I was about 12 years old and started programming first games for 8-bit computers. It was derived from Fuka + soft[ware] and is supposed to be pronounced Fooksoft (again, foo is short). I really don't remember if I had any idea back then (in the year 1980) what certain four letter English words mean, but if I had, I didn't care. (BTW, Fuka is certainly not usual Czech name and Frantisek means Franciscus or Frank.) I really don't understand how publisher's PG language guidelines can allow change of the copyrighted material.

Thank you very much! I never heard about this. But, technically, they surely didn't own the written permission of Shanghai's author (1) to do the changes (2) to distribute in on a cover tape (3) saying that it really is a PD (public domain title) Let's imagine that somebody take Manic Miner, change the in-game text to let it say this is Manic miner by p*ssoft, it is public domain, and then give it to Your Sinclair. Do you think they are allowed to publish it? (And change the name of author.) I think they need a written permission in each case, regardless what's written in in-game text. Frantisek Fuka aka. Fuxoft told me today, that he don't know that Shanghai was ever published in any magazine. It is a completely new information to him. (I didn't ask him whether he is lucky, or angry... :-) He just told me that he remembers they published another his program without a permission, and changed the text too, especially removing any notice that the author is Franisek Fuka and his origin is Czechoslovakia.

When someone wrote into the letters page to ask why the name got changed, that was more or less the reason they stated. It doesn't matter whether that the name wasn't chosen with any intention of being offensive, it's just that to an English reader, there's only one way of pronouncing the word spelt Fuxoft and that is clearly inappropriate for the pages of a magazine intended to be suitable for children and teenagers. Your Sinclair *did* have a history of changing some of the programs which went onto the Smash Tape - for similar reasons, removing swearwords from scrolly messages, for example. Now - those demos were usually referred to as P.D., a legal term which would give YS every right to make those changes. But are they really Public Domain? The authors usually called them such, but also put copyright symbols on it. This is legally inconsistent, but a lot of people did it, and I can see how YS would have difficulty making the distinction between PD and Freeware, especially in the case of an author (who had done P.D.

Fuxoft [Re: Still no tapes received]
If a program really is PD, then they don't need permission to distribute it. I only wanted to say that YS didn't knew it. I mean even if it was PD, they [YS] weren't sure, unless they asked the author. You cannot believe to the in-game text. Is my opinion now clear? his origin is Czechoslovakia. We both think there is no reaon of removing the country name. Did the program previously say that, and end up not saying it? Frantisek Fuka told me, that ALL texts of his 128k demos Fuxoft Soundtrack part 3 or 4 were removed, including the country of origin. I don't know what issue of what magazine it was, otherwise we could possibly compare it to the original version.

Still no tapes received
Hello everybody, A few days ago, I asked here if somebody could possibly send me his Sam Copue tapes in TZX format to let me test them in emulator. Up to now, nobody sent me anything :- Yesterday, I played around with TZX files, and it seems pretty well. You can use Ramsoft's MakeTZX utility (downoad from www.WorldOfSpectrum.org). It is assured to fully support Sam tapes. I tested it and it works 100 correctly with my 15 years old cheap Sony HF-90 tapes! :-) It's simple, but very good. I will definitely add TZX support to emulator (ASCD for sure, maybe also SimCoupe if Simon Owen will let me to do so :-), because it supports blocks 65535 bytes, and that is the major problem of TAP usage on Sam Coupe. So, please send me some tape images. At last! I have only some test files I personally save on my real Sam Coupe. They works, but it's not enough for real testing. Thanks. /-- Aley

It loads only DOS from the switched disk, returning to the original disk for the AUTO* file search (if required). In the options you just specify the path of the disk image or .SBT file containing DOS. Does that fit your requirements? It might even be nice if SimCoupe had a built-in DOS image so the option could be enabled by default, to help out new users... Si

Re: How ROM knowns wheter a disk is bootable
Nice. :-) I would possibly add an option to ASCD to create such better disks where DOS is outside the first 80 tracks. But how to do it exactly? What procedure uses the regular SAMDOS2 to load itself? It uses the standard procedure? I mean does it check two last bytes of each sector to find the next one? I am suspicious about this. As fas as I remember sometimes I had hard times trying to add a DOS to a nonbootable disk, and I always though it is not only the first sector, but whole SAMDOS what must be placed at the start of the disk. Or maybe the sectors must be used one after another? Anybody knows this? It is different in MasterDOS.

Re: Let's discuss ZX Spectrum games
The only problem is that most of the stuff on discs was only ever in that format and sequential format like TAP is kind of no-sensical - what happens when you want to write the high score table back to disc? Update a file? Discs was (and still is) the standard way of distributing SAM software. The only reason for any TAP support must be to archive the Flash! tape, the SAMDOS tape and the two games ever released on tape in a reproducible format. I dodn't say we have to use exactly TAP! I just wanted to say that a file-based format could be better than a physical copy of a sam disk. If you don't like TAP, I can offer you ZIP or something... We can store all additional information (like start line number of a basic program) to file names inside ZIP. If you ask how to load and use this TAP or ZIP, I say: The emulator (or another utility) simply copy these files to a disk, add samdos2 image and auto loader, and boots it. The advantage of a file-based format si that it allows to combine several programs, i.e. to put several different programs to a single disk. If you have a file-based archive, you know exactly what files belong to a program, and you can work with it easier. There is no practical reason for having separate single-file archives (as opposed to discs). The extra amount of a compressed SAMDOS2 file takes is a minuscle 7K and if one is unhappy with the layout, one can always change it oneself. :) I see this reason: It is very convenient to have 15 games on a single disk (if they can fit there). To have 15 different diskettes for 15 short games was never very popular approach. You don't see this reason practical? From the server point of view, I think we can always store a classical DSK/SAD disk image, and add any other file-based archive as a secondary source, if somebody would be interested in using it. /-- Aley
Re: Sam Coupe TAP files
I know SAM and ZX header length are not the same so when a spectrum(emu) tries to load a SAM header there will be a checksum error and it will try the next part in tap file. Correct me if I'm wrong. There is no checksum error. Headers have different ID (ZXS uses 0 for header, while Sam doesn't), so ZXS will never load a Sam header. Reversely, Sam ROM uses a very special approach resulting in that it actually loads anything from either ZXS or Sam. I implemented this into my handler too, so if you put a ZXS tape into ASCD, it will load in Sam mode (but you get nonsense when loading Basic program). Summary: ZXS and Sam tape images can live together. /-- Aley
Re: Let's discuss ZX Spectrum games
I don't think SAMDOS should be on each disk. It is convenient for using the disk with simcoupe until simcoupe has a 'replacement boot' feature (hint hint !) that boots dos from a virtual drive when attemting to boot from a nono bootable disk. Edwin I think that in the real world a DOS is on each disk (or at least 98% or so). Having 32KB ROM full of rarely used stuff instead of DOS is one of the biggest mistakes of Sam designers. (I remember Atari ST did the same way when it was launched back in 1985. But the initial mistake was detected soon after and replaced by a different ROM containing DOS inside.) I would rather let tape users load basic from tape, than disk users to load dos from a disk. (Big sorry to all tape users... :-) I think that booting from a virtual disk would be very good. Wow, who will implement it? :-) /-- Aley

Re: Let's discuss ZX Spectrum games
Thank you Frode. I hope someday I will have spare time to extract these disks and look what's inside. :-) --- I must add that this GoodSAMC is a holy nonsense. Sorry that I complain once again, but really - eh - where is any good point in having all these non-official ZXS games compilations in a disk database? I bet every one of us have got his own 10 or 30 ZXS disks. Should we have all these compilations listed in GoodSAMC? I don't think so. The software like GoodSAMC is good for MAME or similar projects, where it is used only for official ROM releases which are always the same. But using it for private nonofficial ZXS games compilations? Hey, I call it silly. --- And as for archiving software, I would vote for a file-based format, like TAP or something silimar. If we had a litte smart utility, we can automate the copying of whole programs from one disk to another one. And what in the fact is program? I think it is a set of files. And what is TAP? It is a set of files in particular order. The only difference of disk-based set of files to a tape-based set of files is that you can't use LOAD when working with a disk (a filename must be specified), and you must store files in a specific order in a TAP to have them loaded correctly. Okay, it is a bit different. Maybe we could go another way: What about having a standardized logical disk contents format, which will in its basic form act as a regular DSK/SAD file, but will be stored in always the same way what will allow simple automatic copying of multiple source disks to a single disk. What I'm talking about is if we store a single program per disk, it will be OK for emulation. And I thing it is preffered over unofficial compilations. But if we'd be able to automatically merge these disks into a disk containing all-in-one, that would be better for real Sams. (Having every single 40K proggie on a separate disk isn't very convenient.) btw. Is there a virtual DSK/SAD file system for Total Commander or at least FAR, which would be able to extract files from DSK/SAD or even copy then from one disk to another? I would like to make it if it isn't already done. -- Mgr.(MSc.)

Let's discuss ZX Spectrum games
So what do you think: Are games converted from ZX Spectrum worthy? I mean should they be counted as Sam Coupe games, or not? I assume we can skip regular ZX Spectrum 48k games which can be loaded (if we have got some luck :-) into a regular emulator. As I remember, I made a TAP file based emulator back in 1994, and I am sure many other good emulators do exist, which can load files from ftp.worldofspectrum.org without any conversions. But what about - large games with multi-loading levels converted from tape to Sam disk - AY music converted to Sam Coupe Philips SAA chip - 128k-only games converted to Sam - nonworking games fixed to work on Sam I think these games can be counted, since you simply can't load a tape/snapshot file into an emulator and play it without any changes. I personally made several conversions back in 1992-93, and I am sure other people did as well. So we could possibly build up a nice Spectrum on Sam game database. :-) I found 12 diskettes full of ZX Spectrum 128k and/or multi-load games converted to Sam. I personally did mainly the tape-disk conversions, because it is the easiest part (and I was 13, eh, so it was quite hard for me either... :-). Later I also made a half-universal 48k+AY emulator, which supported 48k+AY snapshot files. Then I also converted some very simple 128k games (they just used 128k memory for AY music). I also have some 128k-only games for Sam, like North South (one of my all-time favourites :-) or Terminator 2. So what do you think, and - especially - what games do you have got?

Re: Another example why I dislike .DSK format
Oh yeah, 819200 bytes certainly is Sam disk, but neither Total Commander, nor Windows Explorer knows it. So when you click on a DSK file, it opens the associated program. This problem is also realted to often used ZIP for everything. Sometimes I think we'd need a tiny universal loader, which will be associated with the particular extension, load the file, examine the contents and/or file size and start the right program.

Re: Loading Sam Tape into Sim Coupe
Why a printer port? That was used inancient ages of emulators. Today you just use your soundcard to load tapes. Especially in Windows, it's technically impossible to use non-DMA sound input, because it would either failed to work or hurt the multitasking system core. BUT! SimCoupe emulator doesn't support tapes, and ASCD emulator supports just simple TAP files. So if you want to use some tapes, you currently must use aconversion program (look at www.worldofspectrum.org) to convert tape to TAP file. And I wouldn't bet it will work 100%, since Sam isn't 100% Spectrum. --Mgr.(MSc.)

Re: Let's discuss ZX Spectrum games
I must emphasize one point: Spectrum file formats used on Sam. They are many. If we look to classci 48k emulation, we have files from WoS database, which I call standard. They all could be loaded somehow to Sam. But there are also several Sam-specific snapshot file types not used at WoS. AFAIK these formats are older than formats used on WoS, so that's the reason they exist. Can somebody help me understanding these formats? (I would preferably make a converter from these old formats to classic Z80.) At least, I know of - The standard MGT/Samco's emulator without ROM. Is this somewhat similar or identical to the +D format mentioned by Womoteam? - This is the most wanted, since I still have got some old snapshots of games which are missing at WoS. - Fidzi's .MUL format. The most widely used one in Czech Slovak republic. :-) - Fuxoft's format - They say this is the oldest Spectrum-on-Sam proper emulator and its snapshot format, but it has registers stored in Sam Basic, so the proper conversion is quite tricky. After appending the registers to the main file, I call this format .FUX and it's the only known and supported Spectrum-on-Sam snapshot format in ASCD.) - My own .AYS used for games with emulated AY music, (it's .MUL with two bytes added at the end).

The tape handling code is quite long, since I tried to keep as much as possible from the ROM code. Even some custom loaders are supported, if they fallback to ROM at least for the core loop. It also needed to emulate some special behaviour of Sam ROM code regarding to ZX tapes loaded into Sam Basic (without emulator). You know, there's a special treatment for ZX tapes loaded directly to Sam Basic. (Tell me who knowed this before? I definitely not.) So this is fast-laod.

Sam Coupe TAP files
Here is some information I already posted a few years ago :-) 1. TAP files are tape images. They contain Sam Coupe files in tape format used in ZX Spectrum emulators. 2. ASCD emulator can handle TAP files. ASCD emulates ZX Spectrum, ZXS 128 and Sam Coupe, and it can load TAP files in all emulation modes. You just load them as you'd with a real tape. (Press F7 (NUM7) instead of F9 (NUM9) to start a tape instead of booting the diskette.) So you don't need 800KB disk image per program. :-) 3. I have converted some software to TAP, since it is much more obvious to have a TAP, than to have a DSK file. When it is a software what has never been commercially sold and is 50 KB in size, I don't see very smart to put it on a separate disk image. Either it is nonbootable, which is crap, or it need additional 10KB for SAMDOS, and is always 800KB in total. 4. Note that original TAP file format can't handle all Sam Coupe files. Obviously, it's limited to ZXS, which can't have files 64KB. So I made a little extension to the TAP format. If the files are 64KB in size, it's the real TAP, but if files need to be 64KB in size, there's a little extension. See ASCD source code for details. http://www.keprt.cz/progs/ascd/ascd096src.zip 5.

ASCD emulator can handle TAP files. ASCD emulates ZX Spectrum, ZXS 128 and Sam Coupe, and it can load TAP files in all emulation modes. You just load them as you'd with a real tape. (Press F7 (NUM7) instead of F9 (NUM9) to start a tape instead of booting the diskette.) So you don't need 800KB disk image per program. :-) 3. I have converted some software to TAP, since it is much more obvious to have a TAP, than to have a DSK file. When it is a software what has never been commercially sold and is 50 KB in size, I don't see very smart to put it on a separate disk image. Either it is nonbootable, which is crap, or it need additional 10KB for SAMDOS, and is always 800KB in total. 4. Note that original TAP file format can't handle all Sam Coupe files. Obviously, it's limited to ZXS, which can't have files 64KB. So I made a little extension to the TAP format. If the files are 64KB in size, it's the real TAP, but if files need to be 64KB in size, there's a little extension. See ASCD source code for details. http://www.keprt.cz/progs/ascd/ascd096src.zip 5. Note that there is also ASCD for Windows. :-) 6. TAP support was done 2 years ago, so I wonder nobody knows... :-) 7. And finally: Tape support is mainly for fun. Sam Coupe games on a tape, is't that funny? I think, it is. :-))) Any more questions? -- Mgr.(MSc.)

One machine is a master (server), and other ones must simply take, what their master says. So works the synchonization. Slaves send their pressed keys with time stamps, master sends back what keys should be really passed to the emulator (with timestamps). Slaves ust halt the emulation until master says it's another 1/50s tick. This way the delay is a few ticks, which is acceptable. (and it's the same as network gameplay on a PC - in Windows games like Doom, Quake, Half-Life etc.) Basically, this is the main idea. It can be optimized, but I think we could start with this basic algorithm. :-) Note that all peers must use the same version of emulator to be able to be in a sync. That's the prerequisity. It's something that has been discussed a number of times in CSS, with no perfect solution. One of the better ones seemed to be to have a master emulation, with the secondary emulation state updated from that. The state does includes the full RAM image (or some sort of delta image) updated frequently, with the secondary emulation continuing as normal in-between. Modern FPS games seem to use that method too, but with the state information being smaller and easier to manage. Simon, you are a bit outdated. I played 1943 shooter in a 2-player mode with a man thousands kilometers far away. And we successfully finished it! With POKE / infinite lives, of course. :-) I added .AIR support even to Win32 SimCoupe, but these changes never went into the original development source code version ;-) That might have something to do with AIR being a closed file format, which isn't compatible with an Open Source emulator! RZX (http://www.worldofspectrum.org/faq/reference/formats.htm#RZX) is much more likely to be added instead, and is already the format used by most Spectrum emulators that have an input recording feature. Actually, AIR was a predecessor of all ZXS recording stuff - it was the first time a ZXS emulator could do the record and playback. I never wanted to send AIR into open source, so the people who liked AIR invented the other thing. I think it's obvious - AIR is for tournaments, it's full of security code, and there's no reason in using it in every single emulator. I just mentioned AIR, since it's an example of that just a 5KB file can contain a 1 hour game play. (This huge compression applies to AIR only, I can't say much about the other format.) NOTE THAT THERE EXIST EVEN SIMCOUPE 0.81 WITH AIR SUPPORT!!! It just haven't been publicly released, since it would be against GNU GPL license without the source code, and against the AIR license with the source code. :-) I think we can discuss it off the sam-users list, since it's too technical for the majority of the people. I just end with my statement: Network gameplay is possible, and is not too hard to implement. /-- Aley

Re: NVG DSKification - complete...
If you really N*E*E*D it, load TAP files into ASCD, and save them to a disk image. But do you? I formerly created all those TAP files by conversion from a DSK. So :-) -- Mgr.(MSc.)
