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:

Reminds me of the 1950's wire wrapping tools I have.

How did you not get lost!? :< Awesome stuff though!!!

[CodeAsm]

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.

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.

[Bad_Ad84]

Id just get a PCB made up =/

But props for crazy protoboarding.

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.

Finding a broken solder joint with a multimeter gotta be FUN.

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. :love-struck: :

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 :)
