I'm currently working on emulating the 4D/20 in MAME, and looking for anyone who might
have actual hardware, software or documents that might help.
Right now, most useful would be some high resolution images of the system boards,
especially the GR1 graphics boards, or even schematics if they're out there.
Appreciate any information or input at all.
