Man, that brings back memories. Can't tell you how many hours I spent playing TIE Fighter on those.
Did you have the first edition, with the AT-to-PS2 connectors? =D
Yep, Big fat AT connector and IIRC serial for the mouse! Meant I kept my AT keyboard and Mk1 Serial Intellimouse (the one without a scroll wheel!) way after pretty much all keyboards and mice were PS/2!
