Москва-128

[Shockwav3]

I'll give that a try ... about schematics, I've been largely using this one, albeit having some small errors/deviations: https://github.com/romychs/moscow-12...128_v1.1.1.pdf

EDIT: Some kind of progress I assume after adding diodes for D0-D4 of the keyboard. Sometimes I get the testcard on bootup, sometimes the keyboard can be used with keys being dropped, but hey, the SRAM (6116-15) outputs random characters at random intervals. I guess adding some kind of latching busdriver (IR22?) for the output of the SRAM probably isn't a bad idea either?
