I seem to recall that the CDTV keyboard was just a painted A3000 or A4000
keyboard. Since I have neither computer, I can't tell you if that's so or
which keyboard (since I forgot), but I'm reasonably sure it was confirmed
by other users. The bigger issue may be the non-standard (for A500/A2000s,
anyway) connector, which is a mini-DIN of some kind. Check the mail order
outlets, especially those that handle CDTV/CD32, such as Computer Answers,
Creative Computers, Better Concepts or even Grapevine Group.
