I just removed the B-100 from my glider over the week end. It is a first generation flight computer using GPS from the early 90's. It is the A model (no flight recorder). The software was developed by Dave Nadler who then used the same framework for the ever popular Ilec SN-10. Comes with 2.5" vario with dual needles, 3" screen with a hand controller. Included is a link to an Australian gliding club who has one in their gliders (http://www.waikerieglidingclub.com.au/b-100
