Current MAME driver is here, with my current discoveries:


It sounds like the device is some kind of video overlay thing (teletext type / vcr control type systems?) with internal ascii rom so you might just be able to throw a fake ascii rom in, and patch the checksum code until it's dumped? (or it might be something standard?)
