Krista uses a Kaypro to defeat the security system of a jewelry company the she is testing. The Dracos 3 computer at Robin's Nest also uses a Kaypro keyboard.
Year of feature (shown above)
I just noticed... that Dracos 3 Kaypro keyboard is not even plugged into anything. (wireless? ;)
The Dracos 3 seems to get an "upgrade" in season 7 ("Paper War") because the Kaypro keyboard is replaced with an IBM PC/XT keyboard.
More irrelevant trivia... in season 6, the Dracos 3 has a Kaypro 16 keyboard. So, it went from Kaypro 10 to Kaypro 16 (white keys) to IBM PC/XT. That Dracos 3 has quite a keyboard compatibility feature.
(...maybe that's why it costs "$100,000" ;)
In the season 6 episode "Mad Dogs and Englishmen", the Dracos 3 has an Amiga 1000 keyboard. (again, not plugged in)
So that makes four keyboards for the Dracos 3.
