Xbox runs DX and a modded Win2K kernal if I remember so what is it?
The Famicom (Family Computer?) Nintendo battled over that one, runs F-Basic could have a keyboard and disk drive.
The Mega Drive has a modem, mouse & keyboard availible.
Snes has a mouse & modem, don't recall a keyboard or anything.
CD32 odd one computer insides, computer add ons, yet a console?
Playstation has that Yarooze dev kit thingy (keyboard etc)
Then theres Playstation Linux.
This is gonna get much worse before it gets better :P
