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.

I scan it page by page. No ADF. Most work come afterwards: trying to realign the pages, remove artefacts, clean it up, try to minimize filesize. The whole process is therefore slow, 30 page per hour from paper to pdf is when it goes fast and the original is of good quality and simple A4.


Ok, now there are MSX-BIOS sources, but is there some MSX-BASIC source as well?

Not official ones. And no non-official ones I know of. Closest is disassembled source of other Microsoft Basics like the TRS-80. See www.trs-80.com for that.


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.

There are some diskroms sources on my website. Some are very good at giving insight what a diskrom is about.
And please publish that disk-creation pack!

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.
Great!!!!!

HansO - did you ever get to scan that MSX2 listing?

That's recreated. The ones HansO and Erik Maas talked about were the originals, with the original comments...

Is there anyone who still has a copy of the complete listing? I bought a copy of HansO years ago but it contains only half of the listing.

And is there anyone who has an orginal copy of the MSX2 technical databook? I have never seen one.

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.

This is a nice pop up post from the past...

I think we should celebrate those 15 years that zeilemaker54 used to disassemble and make us all aware of our beloved MSX system internals. On this post it was still all just a plan, but now we are literally much wiser.

I combined HansO’s scans with the pages rotated for readability, and posted them here.
