how old is this shit

[Opry99er]

Pretty freakin old. The console was made in '82, the number pad, who knows. :)

I wonder how difficult it would be to use an Atari CX85 numeric keypad instead? I have a spare around here somewhere... ;-)

Did you ever get this thing figured out? If so, I'd like to see some schematics

[tursilion]

I'd be happy to take a look at it, probably I should finish my PS/2 keyboard. hehe. :)

Hey, awesome job on the EPROM Arcturus cart with jon. I'm glad you guys are around... gives people like me something to aspire to. =)

That's great; I'm back into using my TI with a new 3.5 floppy drive and a cable using the TI with the RCA plugs on the TV.

Thanks... I wish I knew someone who knew hardware so that I could get a schematic on how to modify OTHER TI99s with this number pad. Maybe someone on the Yahoo UG. We shall see!
