My last project (2011 and 2014) for SAM Coupé was an improved remake of Barry Jones' _Jolly Roger_ (1984), written in Sinclar BASIC for ZX Spectrum, an old but nice simulation/strategy/adventure game with some touches of arcade, which I liked. The port to MasterBASIC worked fine and looked promising (http://programandala.net/es.programa.bandera_negra.mbim.html). I used my MBim preprocessor for MasterBASIC (http://programandala.net/en.program.mbim.html), which makes things much easier and lets a cross-development of sorts.

In 2015 I rewrote the program in Forth with my Solo Forth for ZX Spectrum 128 (http://programandala.net/en.program.solo_forth.html). It's called _Black Flag_ and progresses very well (http://programandala.net/en.program.black_flag.html). By the way, Solo Forth runs on several ZX Spectrum models and clones with G+DOS, +3DOS and TR-DOS, and I've considered supporting also the SAM Coupé with MasterDOS in a future version... but I think ZX Spectrum Next (http://specnext.com) will be the _next_ target...

How to manipulate data files in assembler on G+DOS?
Sorry if this is a bit off topic, but I think there are SAM users who have experience with MGT's GDOS and G+DOS for ZX Spectrum. I need to implement (in assembler) two file operations: - Read and overwrite any 1-KiB block of a file. - Read and write text lines sequentally. G+DOS does not provide hooks or routines for these operations, so they have to be implemented ad hoc. I know Andy Wright's Beta DOS included support for serial and random access files, but there's no disassembly available. I've searched the Microhobby magazine, which included many articles on GDOS and G+DOS, but there's nothing about this issue. I still have to finish searching the Format magazine. At the moment I'm studying the G+DOS disassembly, trying to identify the required low-level routines. I wonder if anybody has tinkered with this before and could help with an example code or any information. Thank you. -- Marcos Cruz http://programandala.net

disassembling SamForth
Hi all, SamForth seems a clever implementation of the language. Forth words are direct Z80 rutines (contrary to many other 8-bit implementations, the Z80 stack is used as Forth return stack and the Forth data stack is handled apart), thus Z80 code can be easily mixed with Forth code. Unfortunately its sources are lost. With some changes (e.g the way handling the Forth sources) and updates (e.g. some missing features already present in most modern Forth systems), SamForth would be very interesting for cross-development: the easy of MasterBASIC combined with machine code speed. I've started to disassemble SamForth, as a background slow project. It will take a lot of time because of course the disassembler needs to know what is Z80 code and what is data. Every Forth word in the dictionary has a header before its code, as usual in most Forth systems. Therefore all those data address ranges must be marked by hand first. For example: drop_header: start 0x921b end 0x9221 type bytedata interpret_header: start 0x9224 end 0x922f type bytedata bracket_find_header: start 0x92e0 end 0x92eb type bytedata number_header: start 0x93cc end 0x93d4 type bytedata Has anyone tried this before and maybe has some information to share? For John Avis: Do you remember the meaning of the two bytes before the name length in the word header, or any other relevant information not included in the docs? Everything can be eventually found out from the Z80 code, but any information would be helpful and will save time. Thank you. Marcos -- http://programandala.net

Which colors for a grayscale?
Hi all, In order to automate and simplify as much as possible the process of importing images into the SAM and avoid the palette conversion problems, I'm tinkering with the Netpbm raster formats (http://en.wikipedia.org/wiki/Netpbm_format). BMP and others could be used too, but Netpbm files have two encoding variants (ASCII and binary) for every type (PBM, PGM and PPM), what makes them very versatile in this case. The Netpbm images are created with Linux tools and the SAM does the final conversion, PLOTing the image pixels with the desired equivalent colors and GRABbing it. The first tries with a grayscale image look promising, but I need to choose 16 grays from the SAM palette (0, 7, 8, 15, 112, 120, 127...?) I'm afraid there are less than 16 gray tones, and blue must be used to complete the set. Am I right? Does anyboy know which are the best 16 SAM original colors for a grayscale? Thank you.

text spooling
En/Je/On 2012-11-16 14:41, Simon Owen escribió / skribis / wrote : I'll add file spooling for non-Windows platforms, and clipboard paste once SDL 2.0 is supported. Great! It will be possible to code in MasterBASIC with a modern editor. Cannot wait to try it :) The Windows version will likely remain clipboard only, since sniffing the encoding from text files is just too unreliable. I don't use Windows, but your comment about file encoding makes me think the text is converted before auto-typing it. Isn't it? I mean non-ASCII characters. When I wrote my MBim toolkit I considered how to write SAM-specific characters in the source (e.g. block graphics and UDG) and non-ASCII charers whose code is different from the current 8-bit standards like ISO-8859-1. I solved the first problem with the simple notation used by BASin (the old ZX Spectrum IDE for Windows). For the second, I simply used ISO-8859-1 in the source. Then my Vim converter translated everything, the BASin notation and the ISO-8859-1 non-ASCII characters, to the actual SAM characters. The text was ready to be KEYIN-ed. So far so good. But I think automatic translation during spooling has some drawbacks: first, it would be useful only for non-ASCII characters (mainly, foreign language letters) provided by the SAM (mainly, by MasterBASIC) --or for all characters, in case the file is encoded in any ASCII-incompatible format, e.g. UTF-16, what is not common; second, it could ruin an ad hoc character translation done by the programmer in the source. Example: The charset provided by MasterBASIC lacks four Spanish letters (uppercase Á, Í, Ó and Ú). If I use them in the source (I mean, in the texts managed by the program; the comments are irrelevant), I'd have to choose what character codes must represent them, how to translate them before spooling and finally how to design those missing chars as UDG. Automatic translation doesn't help because those characters are not part of the SAM charset, and my own characters codes could be misunderstood by the file spooler as part of an UTF-8 multibyte character. Therefore, in my opinion, a simple and versatile option could be: first, assuming the spool file is encoded in an 8-bit ASCII-compatible charset (the actual encoding is irrelevant); and second, feeding it as is to the SAM, without translation (of course beside end of line and maybe other control characters).

buggy KEYIN; MasterBASIC's tokenized format; buggy RENUM
Hi all, Some time ago I wrote a toolkit to write MasterBASIC programs with the Vim editor (http://vim.org) and import them into SimCoupe (see http://programandala.net/en.program.mbim). It didn't work because the KEYIN command has bugs (in SAM BASIC, but MasterBASIC didn't fix them). In fact, a similar tool for ZX Spectrum's Beta BASIC (see, in Spanish: http://programandala.net/es.programa.bbim) works like a charm: I can write Beta BASIC code (in an improved format with new features) with Vim, and then, with a keypress, convert it to real Beta BASIC and create a fake disk image ready to be imported into the Beta BASIC interpreter. It would be nice to work the same way with the more powerful MasterBASIC... Is there any patch to fix SAM Coupé's KEYIN? I'm afraid not. I thought an alternative: I could write a program to convert the source code into tokenized MasterBASIC and copy it into a SAM disk image. But the tokenized format is not fully described in the Technical Manual or the MasterBASIC User Manual (though many details can be found there and others are similar to the ZX Spectrum format). In theory this approach is feasible, but much more complex. Any other idea? I'd like to develop some project in MasterBASIC, but its own editor would be a pain compared with the features of a modern editor. Beside, also the RENUM command is buggy, what is a serious limitation. Marcos -- http://programandala.net

I then auto-typed the contents back in to a freshly reset SimCoupe, What do you mean auto-typed? Text spooling? AFAIK SimCoupe lacks a file spooling option (in fact it is what I need: SimCoupe to type the content of a text file of the host machine). I noticed your program also uses labels, though not as many. It might be worth trying to remove the labels, to see if that magically fixes it? I think I tried everything I could imagine when I developed the several versions of MBimport one year ago. Nevertheless I've just written a new label-less version of MBimport. It's easy to remove the two or three labels of the importer, but it makes no difference because there are many labels in the imported KEYIN-ed code. I'll remove them too --just to see what happens.
