I'm hoping someone out there has some details of the rear expansion port.
I'm thinking of making a portable TG-16 with built in screen and yes I'm
aware of TurboExpress. My plan was to have one with *bigger* screen and be
held horizontally like Lynx and Game Gear and not vertically like
TurboExpress is. Plus if I can figure it out, I could even try for a
portable TG-16/CD combo. Before you say that might be too big, someone
already made an handheld version of play station and it's small... It was
just announced today by the same guy that invented portable Atari VCSp at
