Don't forget the two and three-button variants of the A3000 "pregnant" mouse. When I got my A1200 back in the day it came with a three button mouse which was originally designed for the A3000T - the cord was designed for that thing, sitting on the floor, and felt like it was every bit of 8' long. One of the best mice I've ever owned!
PS - anything with the square logo over the I (like in post #8) has to be 1995 or later. Probably just a rebranding of some other commonly available mouse at the time that got a logo slapped on it and bundled with systems, since AFAIK AT didn't design any new hardware (besides the Walker, lol).
