Nobody seems to care about MSX here, let me get started and try to interest you ...
... With some homebrewn stuff I have been assembling here for it:
SCC + MSX Music + PSG (AY-3-8910 compatible YM2203) soundcard for Japanese MML programs such as MuSICA/OPX and MGSEL:
Poor picture of a OPL4 and V9990 graphics boards I build in 2003/2004:
Self built CXA1145 video encoder being used on a upgraded (from MSX1) MSX2 computer:
Playing ALESTE (ROM CARTRIDGE) in it !
HOLY SPAGHETTI !

Reminds me of the 1950's wire wrapping tools I have.
Awesome :P
Also, an msx1 to msx2 upgrade, its only sound and video? I have 1 spare msx wich im willing to "upgrade" some new stuff into.
(Actually I removed some mod the previous owner did.)
By the way, Aswesome build you have. Lets give msx some new life on these boards. :D

The "victim" was an Phillips VG8020 (which is actually an Kyocera made japanese Computer which was re-badged and sold by Phillips of Netherlands) where I replaced the old TMS9929 (first I changed it to NTSC since I live on a 60hz country by replacing it with a TMS9928) with a V9938 and changing the system roms. I also put 1MB of memory mapper on it using Hitachi Pseudo SRAMs I salvaged from some corroded/deteriorated/weathered Virtual Racing arcade board I got from a friend.Originally Posted by CodeAsm

I saw these when I was in Brasilia and the wiring is an art in it's self. I would hate to have to repair one... Next time I will see it working...
The MSX does need more love as the MSX 2 was a fantastic machine.
Like anyone reads the rubbish in the signature.
I can't say I care much about the MSX, nice work though.
I like the sound of the OPL4, too bad no PC games are supporting it...
Finding a broken solder joint with a multimeter gotta be FUN.
<- can someone please make this as a repro and sell it so me?
It's actually simpler than what you'd think it is like. All you need is memorize the pinout of the TTL chips you're using and have a good view of how the circuit works.
The chips on that board are mostly connected in parallel like if they were in a piggy back.
That board is a slot expander. It takes two 8 bit registers it implement and apply redirections to 4 fields of memory based on the contents of the said registers.

I care a great deal about MSX :) Tout ma jeunesse in France!!! I have a Yamaha YIS503F boxed that would love an upgrade to be an MSX2, Vampire Killer power!!!
Maybe this vacation I return to my old msx and restart some programming.
also I have this, my dad isnt using any of the msx stuff and I now own it.:

MSX will always have a place in my heart.
I grew up playing gradius, kings valley, penguin adventure, and all the great msx games.
Currently I have a msx1 and a spare gradius 2 cart to mod and user for scc sound cart.
Penguin Adventure really stood out for me, brilliant game. Loved the Goonies, Road Fighter and F1 Spirit too!!!
I would run a OS like UZI180 I had a Master System and all 3 CPCs in varying conditions and dreamed combining them into a MSX .
Nice msx-warez! :)L_Oliviera:I and I think many more would be happy if you had any schematics / info about those pieces of homebrew hardware.. I know some is available online, but not all, I think. Code asm:Well, I think you actually need RTC for true MSX2 standard,. Also, for msxdos 2.2x you need >= 128 k ram (not a part of the standard tho, but a verry nice upgrade :)
roots on MSX;

-Metal Gear
