Re: Diskdrive of 8245 broken... HELP! !?!?!?!?!??!
HI! I'm still trying to fix this bloody drive! I found out some new strange behaviour: Manuel Bilderbeek wrote: Manuel Bilderbeek wrote: I've been researching some more on this drive, and found the following: - If I'm lucky, I get a disk formatted with it (single sided and double sided). Sometimes it gives a disk error, when it's writing the bootsector, but after retrying it always seems to work) - I can save and load files on disks formatted with this drive most of the time. Sometimes I get Disk Offline messages. When I push a little bit to the drivehead, it works again. - Disks formatted with the 8245-drive cannot be read on other (MSX) diskdrives! - I can not read disks formatted on other drives. (I got this only once, I think) little helps. Conclusions: -Drive works perfectly, but the head seems to be misaligned or something! I was playing with the drive a bit again last night, and found out this... After pushing the drivehead a bit, I didn't get Disk Offline anymore. So I tried to save some files. It worked every now and then. But when I tried to read those files on another MSX, I got Disk Offline again! So i formatted the disk on that other (fine working) MSX. Then I put the disk back in the 8245 and to my astonishment: THE FILES I SAVED WITH THE 8245 WERE STILL DISPLAYED AFTER EXECUTING THE "FILES" COMMAND!!! Yes! After a very hard low level format of the disk!! But when the disk was back in the other MSX, it displayed no files at all. I could even save files on that disk on that other MSX, without any problems, and STILL the OTHER files (saved with the 8245) appeared when executing FILES on the 8245!! The files saved on the other MSX did not appear. One strange thing is that there would always appear a file called "700" when executing FILES on the 8245, which I don't remember saving on that disk... (but I could have forgotten this)... Hmm, it seems that the 8245 is saving BETWEEN tracks or something??? So the head must be REALLY misaligned!? Strange... Note that successfully executing a FILES command on the 8245 still requires pushing the drive head... otherwise it will still give a Disk Offline error. Loading those saved files doesn't work properly, the file-contents is corrupted... But the disk seems to work fine on another MSX... Can anyone explain this?

Re: [Phoenix] Re: Phoenix project - The new MSX platform pro-standarization
At 08:44 PM 7/19/99 +0200, you wrote: I'm not sure turbo R compatibility would be a good thing. You would need an R800-compatible processor for example, and as far as I know Z380 isn't. ??? ISN'T IT ??? I looked up the opcodes for some of the R800 instructions and the Z380 has different instructions mapped to those opcodes. Well, then maybe we can disassemble and adapt turboR-programs. I mean, the only non-Z380 compatible instructions are MULUW and MULUB, aren't they??? The other ones also work on a Z80 (though undocumented). It was some time ago, I don't remember how much instructions are different for Z80 and R800. But it may be the case that Z380 doesn't supports all of the undocumented Z80 instructions. Anyway, those things can be looked up. I bet the Z380 has a good counterpart for MULUW and MULUB... It has multiplication instructions, but I don't know if they're exactly the same. So that shouldn't be too difficult. Just search for the opcode and replace it. Easier said than done. How can you tell apart an opcode from a sequence of data bytes? Example: a byte with contents #3E, does it mean "LD A,n" or does it mean the number 62? Maybe an adapted emulator could report all addresses of executed R800 instructions... Maybe then I can finally play Illusion City! To play Illusion City, is MIDI nessacary? And is the PCM device nessacary??? What other points of incompatibility could it have??? Turbo R ST doesn't have MIDI, only GT has. So I guess Illusion City can do without. I'm not sure if it uses PCM, I played for only a little while. Well, actually I think a 'new' MSX should also have a PCM sampling device, so why not take the tuboR's sampleunit? I'm not particularly font of the way the turbo R's PCM works. Although it's simple in hardware, it's not simple to use. I prefer a PCM device that uses buffering. For example the way MSX-AUDIO handles ADPCM is nice, it plays from sample RAM and can generate an interrupt when it's done playing. The bad thing of a new list is that many people won't subscribe to it, although they may have interesting ideas. Maybe we can use this list and put "[Phoenix]" in the subject? Yes, yes. They do that in the int-fiction newsgroup too!!! Only one thing: A lot of people are subscribed to the newsgroup but not to this list (I can understand that, sometimes the message-flow is a bit much here, while you can skip them in a newsgroup. Although the subjects are way more interesting here...). So I think we should find a solution to that... It's possible with some mail programs to post on both. Manuel does it all the time. But ofcourse not everyone uses an integrated news and mail reader. Actually, do you think there are people on the newsgroup that are not on this list and want to participate in the Phoenix discussion? Most newsgroup people are either interested in emulators or in chatting. And if there are interested people, they can simply subscribe to this list. With all the web-based free e-mail sites, it should be no problem for someone with net access to aquire an e-mail address. And anyone with a little advanced mail program can filter messages, to separate this list from personal e-mail, or even separate Phoenix messages from the regular list traffic. Will a web-based forum work??? No, I can tell from experience it doesn't work... Although... I don't think it will be visited really frequently, like a mailinglist, which you are forced to pay attention to. ...And that's the reason why. Maybe someone should put all or the important messages concerning Phoenix (so with [Phoenix] in the subject-line) online on the Phoenix webpage, or something like that... We could make an archive of all messages and put it on the Phoenix site. Does Sean still do this for all messages on this list? And maybe someone can regularly (once a week?) make a summary of the discussions. Those summaries would be posted on a separate section of the site. It's not about bookmarking I think. you should be able to remember it, to tell about it to others... OK, mailing the URL is one extra step, which might be problematic if more people have such a poor memory as I have. Bye, Maarten MSX Mailinglist.

More about HC-95
People,
1. Yes! This MSX was made by JVC, or Japan Victor Company... :)
2. This computer uses a Hitachi processor that works like a Z180. And
this computer has a hardware switch to change between Z80 and this
chip HC{something}... :)
3. This computer is a MSX2, has MSX2 in case... :)
4. Inside HC-95's case you see to large board (with the same size),
one has CPU, PSG, RAM and otherthings and the other has a video
board.
If I'm not wrong this computer don't is fully MSX compatible... :)

Re: [Phoenix] Re: Phoenix project - The new MSX platform pro-standarization
I'm not sure turbo R compatibility would be a good thing. You would need an R800-compatible processor for example, and as far as I know Z380 isn't. ??? ISN'T IT ??? I looked up the opcodes for some of the R800 instructions and the Z380 has different instructions mapped to those opcodes. Drat. (I like Dexter) Well, then maybe we can disassemble and adapt turboR-programs. I mean, the only non-Z380 compatible instructions are MULUW and MULUB, aren't they??? The other ones also work on a Z80 (though undocumented). It was some time ago, I don't remember how much instructions are different for Z80 and R800. But it may be the case that Z380 doesn't supports all of the undocumented Z80 instructions. Anyway, those things can be looked up. Well now we know thay do. I bet the Z380 has a good counterpart for MULUW and MULUB... It has multiplication instructions, but I don't know if they're exactly the same. Mwa... I think so. Only other opcode I think. So that shouldn't be too difficult. Just search for the opcode and replace it. Easier said than done. How can you tell apart an opcode from a sequence of data bytes? Example: a byte with contents #3E, does it mean "LD A,n" or does it mean the number 62? Maybe an adapted emulator could report all addresses of executed R800 instructions... No, no, in contrary. It's quite easy. First, all those instructions have multi-byte opcode, don't they? Do the chance you get something wrong is already minimized. Second, you can look at the byte before it. If it's the opcode of an LD HL,nn-like instruction the it probably won't be the instruction you're looking for (unless the programmer used 'nested' instructions, which is not used often though, only in BIOSses). Next, you can show the surrounding code and if it makes sense, then it's a REAL multiplication-instruction. If it doesn't, it's probably data. It might even be possible to let a program automatically decide if the surrounding data is code... Also, I don't know what the opcode is, but I think it's not a simple one, so it's highly inlikely that the opcode will be (referred to as) data. Maybe then I can finally play Illusion City! To play Illusion City, is MIDI nessacary? And is the PCM device nessacary??? What other points of incompatibility could it have??? Turbo R ST doesn't have MIDI, only GT has. So I guess Illusion City can do without. I'm not sure if it uses PCM, I played for only a little while. Oh. Well, Daniel says it did. Well, actually I think a 'new' MSX should also have a PCM sampling device, so why not take the tuboR's sampleunit? I'm not particularly font of the way the turbo R's PCM works. Although it's simple in hardware, it's not simple to use. I prefer a PCM device that uses buffering. For example the way MSX-AUDIO handles ADPCM is nice, it plays from sample RAM and can generate an interrupt when it's done playing. Yeah, okay, that's cool. But not the OPL4-way, because the OPL4 sampleunit really SUCKS!!! It can play nice samples but there are three disadvantages: 1. The sample always has to loop at the end, you can't just let it stop. 2. Therefor, the OPL4 can't generate an interrupt if the sample is finished, and 3. You can't play sound and access the SampleRAM at the same time. Resulting in a maximum sample-length of 64k (using an 8-bit sample). Therefor, the OPL4 is, although it supports high frequency, high quality samples (16 bit, 44.1kHz), definately NOT FIT to play large samples like .WAV-files. It is good for sounds and samples in games which can be done like 'I tell you to play the sound and I don't want you to bother me afterwards', though. It would be the best if you could tell the sampling-device to generate an interrupt at byte X, therefor enabling the program to start filling the SampleRAM again a short while before it runs out of SampleRAM (although this is not a nice solution, because it could result in problems on future too-fast MSX computers... But let's not assume this). Also, the presence of this device would make it possible for game-developers to support sampled soundeffects for the non-MoonSound users. Ah, and by the way, MSX-programmers should in the future avoid to develop speed-sensitive programs. What I'm trying to say is for example in case of a screensplit: try not to assume it arrived at a certain line after some initializations before the real lineinterrupt, but keep track of the amount of H_BLANKs, even if this makes you to put the screensplit a few 'lines' higher. The bad thing of a new list is that many people won't subscribe to it, although they may have interesting ideas. Maybe we can use this list and put "[Phoenix]" in the subject? Yes, yes.

Re: Bootstrap SP alternate register set cart x-ecution
I read somewhere that the header of a cartridge can/must contain more info than only AB and a pointer. Can someone give me more information about the memory layout of a cartridge. You might consider to buy some books... they're still available on fairs. MSX Handboek voor gevorderden (purple book), for example is a very good (read: useful) one. It has a lot of info in it concerning hardware, the BIOS, RAM-adresses, Basic-routines, ASCII-table etcetera. It has only one big mistake: the subslot-selection is explained completely wrong. The subslot-selection is very similar to the primary slotselection, only using adres # instead of port #A8. There are three books I use a lot: 1. A book about the Z80 processor (by Rodnay Zaks, with the lightning picture on it) describing every instruction, or rather, the complete processor (incl. more 'advanded' subjects like timing or Z80 instruction processing etc.) in detail. 2. The MSX Handboek voor gevorderden I just talked about for every detail about the BIOS, RAM adresses, etc. 3. A hardcopy of the VDP cursus of Stefan Boer. Very useful indeed! And ofcourse I sometimes use additional docs like the Dos2 documentation, and OPL4 documentation, but those are used quite occasionally. ~Grauw "Livin' la vida loca MSX" -- email me: [EMAIL PROTECTED] or ICQ: 10196372 visit the Datax homepage at http://datax.cjb.net/ MSX fair Bussum / MSX Marathon homepage: http://msxfair.cjb.net/ MSX Mailinglist.

Re: Accessing disk with disabled interrupts
Is it possible to execute BDOS / Disk BASIC disk operation with interrupts disabled? Errm... It surely is possible I'm not sure if they keep the interrupts disabled. Actually, I think they re-enable them afterwards. Do those functions embed EIs? ??? I guess so. Should I disable interrupts accessing the VDP register directly? Yes. Like this: LD A,value DI OUT (#99),a LD A,register+128 EI OUT (#99),a Keep in mind that when executing an EI the interrupts will be enabled after the next instruction. So this is the way to keep the interrupts disabled as short as possible, which is always preferred (although not required). Is it legal to call 256 times #FD9F with interrupts disabled at VDP level? Absolutely. But it might re-enable the interrupt. You'll have to check that. Is it legal to tell Disk ROM to stop the motor with VDP interrupts disabled? Yes. Basically the DiskROM has nothing to do with the VDP. Just keep in mind that there is a chance that they enable the interrupts. But why do you need to keep the interrupts disabled??? Kiss you lot.

Should I disable interrupts accessing the VDP register directly? You don't have to, but it does solve the F700 slowdown. Or do you mean "should I use OUTs rather than a BIOS call"? In that case, it doesn't matter. I use OUTs but Konami uses BIOS calls. Is it legal to call 256 times #FD9F with interrupts disabled at VDP level? Yes. The VDP is only accessed by the interrupt handler in the ROM, which decides whether it should call both #FD9F and #FD9A or only #FD9A. #FD9F is only called on normal VDP interrupts, not on line interrupts or interrupts from for example MoonSound. So, if you call #FD9F, there is no problem, since routines on that hook won't check the VDP interrupt status anyway. If you would call #0038 256 times, things wouldn't work.

Jon, pay attention please!!! I had a quite small Compass-program, though very often saved and changed. The size of it was about 65000 bytes. I already though this was absurd but since it .ASM-files are a direct dump of Compass memory I guessed a lot of additional information had to be saved. However, when I copied the source into another sourcebuffer and saved it under another name, the .ASM-file was only 6000 bytes!!! That's a factor 10 reduction in size Jon!!! Explain please???

Re: Diskdrive of 8245 broken... HELP! !?!?!?!?!??!

It worked every now and then. But when I tried to read those files on another MSX, I got Disk Offline again! So i formatted the disk on that other (fine working) MSX. Then I put the disk back in the 8245 and to my astonishment: THE FILES I SAVED WITH THE 8245 WERE STILL DISPLAYED AFTER EXECUTING THE "FILES" COMMAND!!! Yes! After a very hard low level format of the disk!! But when the disk was back in the other MSX, it displayed no files at all. I could even save files on that disk on that other MSX, without any problems, and STILL the OTHER files (saved with the 8245) appeared when executing FILES on the 8245!! The files saved on the other MSX did not appear. One strange thing is that there would always appear a file called "700" when executing FILES on the 8245, which I don't remember saving on that disk... (but I could have forgotten this)... Hmm, it seems that the 8245 is saving BETWEEN tracks or something??? So the head must be REALLY misaligned!? Strange... Note that successfully executing a FILES command on the 8245 still requires pushing the drive head... otherwise it will still give a Disk Offline error. Loading those saved files doesn't work properly, the file-contents is corrupted... But the disk seems to work fine on another MSX... Can anyone explain this? I think you have a head alignment error when the disk is writing to track 0 it's actually writing to track 1 i think the bearing of the worm spindle is worn out (or if some one has been messing around with it the trck0 sensor is misaligned) erik de boer -- MSX Mailinglist.

Nice Gfx9000 idea...
The Gfx9000 can superimpose the image over an incoming signal, can't it??? If that's so then you can create a game/program showing 3-layers!!! The background doesn't move or only moves up and down, which is the v9938 screen. If it's a bit vague, that doesn't matter. It's just a background. The second and third layer are the layers of the P1-mode...

Re: Those Microsoft coders...
Well JPs are a bit faster than JRs. Speed is more important on MSX than space I think. Although in the case of Dos they don't seem to use that policy. And that is perfectly logical.

Re: Phoenix project - The new MSX platform pro-standarization
At 12:56 19/07/99 +0200, you wrote: have the guarantee of a full compatibility between different projects and a It's a good idea to standardize the new MSX efforts, it will Iim sure that Phoenix is something needed for the MSX system, and with Phoenix all the programmers will be in contact with hardware developers to work together. Well, it sounds really good, but unfortunately, as I've noticed in 6 years of MSX-freaking over the Net (and 12 years into the MSX-scene), I don't think it'll be successful. Why? Reasons below. But I wonder, how will the Phoenix standard be decided? As I said Phoenix depends on Internet, there is no discussion about this, therefore Phoenix must be decided in Internet, I will contact with Tristan and Funet will have a Phoenix directory, Padial will publish schemas and complete information about the finished projects. The Phoenix web is another important part. But what about the developers which don't have internet-access??? I know Hans van Oranje has, and others might be able to access the internet via school or the library, but I don't think they all have internet-access. That's the 1st point, hard developers who can't access Internet. 2nd point, hard developers who dislikes e-mails. 3rd point, hard developers who doesn't speak English properly. An alternative to consensus would be voting, in that case who gets to vote? Anyone who subscribes to a Phoenix mailinglist? This is not neccesary, how many hardware developers are in the world??, maybe with the hand fingers is enough to count them, there are many programmers, but the programmers depends on the hardware developers, so the main characters of Phoenix are the hardware developers: Padial, Ademir, Culla, ESE, Henrik... I don't agree with that. Software-developers must also have a "vinger in de pap", because they are the ones who are going to use it, and they can tell which things are useful, which not, and they can give very useful suggestions or tips, for example on a feature which makes a certain board a little more expensive, but at the same time is of a great help to programmers (for example an external interrupt or so). Why a Phoenix mailing list, if we've a MSX mailing list. I don't wanna subscribe to another mailing list, only to know if Phoenix is going well or not. Another question: what are the starting assumptions for Phoenix? Well, this is certainly complicated, I think Phoenix must assumpt the system hardware developments like Z380, new musics board, new VDP boards... Nowaday we have no problems because there is only a new music board and a new VDP board (I think): Moonsound and GFX9000, but it could be a real problem if somebody makes a new OPL4 incompatible with Moonsound, Phoenix has the responsability in this kind of problems. Ah, this is very good. In a lot of projects the OPL4 of v9990 is not listed or is listed but in an incompatible way... I'm very glad with this... relieved. By the way, there was some guy (dunno where) developing an OPL3 board!!! Leonard... Aargh! Let us make it MoonSound-compatible and convince this guy to use OPL4!!! (which can still be achieved). Have you noticed how much a Moonsound board costs? Maybe he chose OPL3 due to the price. Oh, by the way, I think a new MSX must have a decent timer of which the speed can be set and which can generate an interrupt. This is definately useful, in example for JoyNet. Sure! We know that MSX is a generational standard, theorically MSX-TR is compatible with MSX-1, MSX-2 and MSX-2+, MSX 2 with MSX-1...possible new MSX computers have to be compatible with MSX TR, 2+, 2 and 1 obviosly. Ok, that is perfect. Hmmm, hope so. This mailinglist is, I have to say, quite emulator-less... Compare it with news://comp.sys.msx which has a lot of emulator-talk.

Re: VDP port addresses in ROM
Do you guys get the VDP port addresses from main ROM (at #0006) or you actually bang #9x ports directly? We all use #9x immediately. Unless we write a tutorial were we say that the standard asks us to use #0006 ;-) He is right. There is some MSX1 to MSX2 transformer which has different ports but we need the speed too much to read it from adress 6. And in Dos-environment we have to do some difficult interslot-read... nah, assuming #98-#9B is much faster, easier, clearer. Using address 6 forces you to always use the OUT (C),r form, but I've managed to cope with this in a clean way but... the setup interslot-read and unorthogonal incrementing-storing really makes me SICK. It's the worst part of the code and it's right in the beginning! 8:D And by the way, from MSX2+ on, those ports #98-#9B are standarized too. So if you directly use these ports, it will work, according to the standard, on every MSX 2+ and higher. And in practice, it will also work on every MSX, exept for those which are adapted to MSX2 with this very rare Japanese board. And as I have no access to these rarities... perhaps some other incompatibility would arise despite the effort! So #9x is the way. MARK 2 MSX Mailinglist.

So this is the way to keep the interrupts disabled as short as possible, which is always preferred (although not required). Nice tip. This reminds me of the EI/RETI pair back in the ZX era. The fact is that... ***I DON'T REMEMBER THE REASON!!!*** Is this tip used in MSX interrupts? Why (or why not)? ZX Spectrum used IM2. Is it legal to call 256 times #FD9F with interrupts disabled at VDP level? Absolutely. But it might re-enable the interrupt. You'll have to check that. OK. Is it legal to tell Disk ROM to stop the motor with VDP interrupts disabled? Yes. Basically the DiskROM has nothing to do with the VDP. Just keep in mind that there is a chance that they enable the interrupts. But not at VDP level I suppose. But why do you need to keep the interrupts disabled??? It was posted on this list that F700 had disk speed problems because of poor disk interrupts. One way to cope with this was disabling interrupts during disk loading. This way the F700 problem is solved at boot time without disturbing other MSX models and without the hassle of saving/RET poking/restoring the int vector. Kiss you lot. MARK 2 MSX Mailinglist.

Re: Text editor w/ varitabs
Is there any good text editor with variable tabs per line (for assembler readibility's sake!)? Well if you want a text-editor I suggest Ted, very good although it has Dutch menus, which may be a problem (but I think not). Why is it not available in plain english? It's not a big problem but feels a bit uncomfortable and gives software a bit too much of a "public domain" look. But if you're programming assembler: GO GET COMPASS!!! (Yes, I'm shouting!) I'll have a dekko at it (now I'm deaf btw!) 8;) ??? So you want different TAB settings per instruction??? My message was messed up (by your reader or my poster). I don't want different tabs per instruction but per line field. LABEL DJNZ LABEL; FOO LD A,B ; BAR That is, something like 8 spaces per colonless label (so you can fit it in the same line), 5 per instruction (the longer mnemonics HALT, DJNZ, etc. have 4 chars) and a suitable space for comments without touching the instruction paramenters. Well, if you want readability I suggest you drop your entire current layout and go start a new one: Mmm... me and the lot of 6502/Z80 coders back in the very early 80s were using that layout! See Terminator part 1 robot listings 8;) Foobar: lda,b djnz Foobar Some prefer to have the labels on seperate lines because it's easier when inserting/deleting instructions but I don't; the CTRL-L keycode of Compass is very useful. Just like me! It's a bit messier if you have a poor editor, which is not our case, huh? 8;) Also, I use lowercase characters for the code (but uppercase is nice too), and lower+uppercase-characters for Program-labels (like Foobar), and uppercade-labels for data: DATA: DB#FF Well, it's almost mandatory to use lowercase for 68000-like assembler, since it resembles a high level language: FooBarLongLabel movem.l d0-d3/a0-a2/a5,-(sp) * Foo bar loong comment eori.b #$25,$22(a0,d0.l) * Foo bar looonger comment That in uppercase would be DEADLY! But I personally prefer 8-bit assembler in uppercase. It looks more consistent, and opcodes ain't that messy to become unreadable. Again, see Terminator. Robot listins wouldn't be as impressive in lowercase 8;) I really hope you take over these programming-habits because it really makes your source much easier to read, it really makes a difference! As I've said it was a problem of TAB conversion between our mailing programs. My habits are just "classic" early 80s stuff: uppercase varitabs. Nothing that messy. They were actually stroking listings on teletypes so the code had to be real readable! *:D And btw I'm quite proud of my crystal clear assembler. I even don't put a single comment mixed with my code if it's not a matter of life/death! I prefer a short and clear header description, clear labels and equates, the right amount of "air" and choosing only the best way to do things (there's only one, so there's no chance of misunderstanding). I also prefer notes, diagrams and algorithms off the source, even though I'm proud of my ASCII art 8;) Kiss you lot. MARK 2 MSX Mailinglist.

Re: Memory map and interrupts at boot time
At 05:08 AM 7/20/99 +0200, you wrote: What's the actual memory map configuration and interrupt status at boot time (phase 2, after RET NC)? Interrupt status: no idea. I issued a HALT and get frost. Memory configuration: all RAM, with some routines (slot select etc) copied into page 0. But the standard boot code seems to jump #4022 without slot select if MSXDOS.SYS is not present.

Re: Those Microsoft coders...
Disassembling a standard MSX-DOS V1 boot sector I've come across the following: It uses a BDOS function 6 loop to output the boot error string instead of function 9 (!). Any reason? Yes. It probably is a null-terminated string, which sometimes is nessacary if you for instance want to display a '$'-sign, or when you are printing an ASCIIZ-string Dos2 uses for its diskroutines. But this string: C085426F6F74206572 DEFM"Boot error" 726F720D0A DEFB#0D,#0A C09150726573732061 DEFM"Press any key for retry" 6E79206B657920 DEFB#0D,#0A 666F7230726574 72790D0A Has not a single $. Neither DOS2 did exist. It's the bootsector as found in the Philips NMS 8250 MSX-DOS release *1*. I really don't understand the programming style of the bootsector. Really BAD habits. By the way, if you disassemble function 9 you'll see it's nothing more but a loop which calls function 6 until it encounters an '$'. I guess so, but that's precisely the reason to use 9 instead of reinventing it and the wheel! Haven't checked that but I'm quite sure, I know quite a bit how Dos is programmed and I really expect those kind of tricks of them. Tricks? To repeat a ROM function? To use JPs in loopless near jumps??? 8:? There're spurious JPs where it should have been JRs (!). Plenty of space??? *:D Well JPs are a bit faster than JRs. Speed is more important on MSX than space I think. Although in the case of Dos they don't seem to use that policy. But the mapperroutines are as fast as they can get. They get credits from me for that. Faster for an error branch (no S/M code)? Is the whole MS firmware this quality? :) Well looking to Windows...
