It's a 101-key buckling spring Model M, with a trackball mounted above the numpad. PS/2 connectivity via a dual-connector detachable SDL cable which is included. Two-piece keystems+keycaps. Includes an extra plastic retaining ring for the tracking ball and a purple Unicomp tracking ball in addition to the original one. Dated 1995-05-05.
Edit: pictures were lost in the forum rebuild.
I've attached a couple, not sure how or if they'll show up.
I used this for a while and eventually put it away because of two things:
- The tracking ball is supported by bearings, and the places for the bearings to mount are broken. This causes it to track unreliably.
- It has, in the past, sent keystrokes for keys that were not pressed. Keys are seated correctly so I suspect debris interfering with the membrane but a controller fault is not impossible.
Despite these issues, both the keyboard and the trackball
do work. They just don't work perfectly.
