take it apart, solder on a PS2 port and you can attach a PS2 keyboard! You can also attach a C64 disk drive if you do some more soldering. It is literally an entire C64, and all the old outputs are available on the PCB. You probably could stick the PCB inside a (chunky) PS2 keyboard, put some ports on the back of the keyboard and have something that is literally like a C64 of old.
