The MSX BIOS book, published by Quest for ASCII, is now available in pdf format. This book contains the well commented, official and original source listing in assembler format of the BIOS of the MSX 1 computer. This gives a detailed inside look in the MSX system.
I had some requests for parts of the book and recently obtained the (once very expensive!) original. So I deciced to scan the whole book and publish it.

Really nice! Now someone should convert it to ASCII so, that we can compile it Smile

On a MSX fair in Tilburg some years ago, I got a few Philips ordners with MSX documentation. One of them contain a part of the MSX2 listings. I have paragraph 1 till 15, but 16 till 24 are missing :-(
Most of the listings are printed on the 5th of June 1985.

So, if someone has the ordner with the last part of the MSX2 listings, we can make it a complete listing!

The parapgraphs have the following titles:
Paragraph 1 till 15 : MSX2IO, MSXIO, BIOENT, BINENT, IMPOSE, MSX2HD, BIO, MOUSE/CAT/LIGHT PEN, BIOBAS, SLOT, INITIALIZE, JMPTBL, CASET, DEFINE and TT.
Paragraph 16 till 24 : SLOT, V9938 DRIVERS, ROMAJI, MSXINL, BITBLT, MSXCHR, MSX2GRP, MSXGRP and MSXRAM.
(before someone asks about MSX2HD, for some reasons the header in this source contains : THESE ARE THE ROUTINES CALLED INSIDE THE BASIC INTERPRETER AND THE SYNTAX TOKEN DEFINITIONS REFERENCED Smile )

By the way, there is something remarkable if I compare the MSX1 BIOS entry listing with the MSX2 BIOS entry listing. The MSX2 BIOS entry listing uses 8080 style assembly! e.g. JMP, MOV, LXI, RZ, CC, etc. It appears in some listings, but not all. (phew)

Hey erikmaas, I have three Philips ordners here - I believe the one you indicated is among them. I don't have much use to it anyways, so I figure I could bring them along to some fair sometime... Are you planning to go to Nijmegen 2006?

I have these documents also, including the missing parts. Quite a thick pile of parts of the MSX 2 BIOS. Lts of pages to scan, which I plan to do some time. Alas the listings are just parts and first evrsions, not a complete listing.

Microsoft and ASCII used a cross assembler in those days, running on a mainframe like Digital Equipment DEC10 or DEC20 with the TOPS operating system. That cross assembler was, typical for CP/M times, for the Intel 8080, hence the mnemonics. Nearly all of the CP/M software was for the 8080.
For the MSX BIOS listing book the mnemonics were rewritten and the source assembled with Z80 mnemonics.

Hans: What kind of scanner do you use? I can access a scanner which will eat the whole stack of paper by itsself and hopefully outputs some useable data. So, it would not take too much of my own time.

D-Tail: I will go to the Nijmegen fair. But to be honest, I have not used any MSX documentation the last few years. The only reason I am interested in it, is to be able to make it digital. If Hans will do that, then I do not need your part of the documentation.

About the listing: I did also figure out that this is not really the latest version, comments like "; Here comes the ....." give some good indication Smile
But, I would be very surprised if the final code has changed dramaticly.

Ok, now there are MSX-BIOS sources, but is there some MSX-BASIC source as well?
Or maybe some DISK-ROM source? For the latter one, I do have some DISK-ROM creation pack which contains DISK-BASIC 1.0 in some .REL files. You only have to add the hardware specific code for which there is some sourcecode included.

Soon I will publish my sourcefiles (disassembled from orginal roms) for MSX MAIN BIOS, MSX BASIC, MSX SUBBIOS, DISK kernel 1.00 and DISK kernel 2.31. Currently, I have requested a special sourceforge project for this purpose.
