I have being in touch with a gentleman who might be interested in producing some PS/2 (and maybe USB?) he is looking a schematic and a program for the PIC/PLA or what ever device would be used.

There're several projects with schematics:

Looking for something cartridge based, like the padial one was.

So then you have this: https://github.com/S0urceror/MSX-USB
More details in this MRC thread

No idea about its maturity; but seems that USB HID keyboards are supported. S0urceror is an active MRC user, maybe he can shed some light.

A board design is nice, but then the programming off the chip is also key, the LPE adaptor just plugged in and required no additional commands or user input
