Nice project, MSX2 is a great machine. I don't have a lot of knowledge about
electronic to help but there are plenty of MSX oriented websites out there
(
WWW.MSX.ORG for example) where you can post about your project and ask
questions.
Good luck and keep us posted on your progress.

Subject: Looking for MSX2 expertise
Hi
As you may already know, at the N8VEM project we are working on an S-100
VDP. This board has a V9939 video display processor and a AY-3-8910 sound
generator which should allow us to have some MSX2 compatibility when
combined with a backplane, S-100 Z80 CPU board, and a memory board.
There are more IO and memory features necessary for full MSX2 compatibility
required though. I am considering a designing a board to provide the
balance of MSX2 functions so that the combination of an S-100 backplane,
S-100 Z80 CPU, and S-100 VDP.
I envision such a board to be composed of SRAM memory, a couple of 8255
PPIs, a card slot plus whatever extra IO and memory we need. If anyone has
detailed MSX2 experience and would like to help out on designing an S-100
MSX2 compatibility board to complement the S-100 VDP please contact me.
S-100 and MSX seem like a neat combination but no one has tried it AFAIK.
Thanks and have a nice day!
