IBM Model 75 Selectric typewriter --
Rare transistional electronic 96 character model, circa 1980, in IBM blue with mechanical keyboard (feels like a Selectric II) and electronic 7500 character (26 documents + 99 phrases) memory. Good condition, types, but needs a bit of TLC (new ribbons, oil?) as it has been stored (indoors, clean & dry) for the last 15 years. $150

Trav-A-Dial bidirectional electronic counter
-- I think this was originally for use with a mill or lathe in conjunction with a 200 count/rev quadrature encoder (which I DON'T have but are available from many sources) to read displacement in .0005" increments up to 200 inches. These use Hewlett Packard dot matrix decimal readouts for a very pretty display. Switches for direction control and reset. Nice cast metal case, requires 5 volts power, 6 pin female Jones connector interface w/pinout provided. $75

Cateye Solar II, Cyclocompute

Shows mileage, speed, plus heartrate sensor

Cateye Solar II, Bicycle Computer, for calculating speed, heartrate, and distance on trips, and many other information for cyclists. Works on Solar Power. I have the optional Pulse Sensor Unit, that detects Heart rate, and feeds this into the computer. This is new-in-the-box, unused. New-Old-stock. The original type that was made in Osaka, Japan. Quality so much better than newer China made types. Has all original items, shown in photo. Never installed, stored in closet, now for sale. I paid over $150 for both items during the early 90's. Asking $50
