I picked it up many eons ago for 20 bucks on ebay. Now somehow it goes for 90-100?? With some people even asking outrageous 200 for it. The specs certainly haven't gotten any better. What is it with this inflation of retro gear prices lately?

The operation manual dates to October '79. It's already driven by a microcontroller, a MOSTEK MK3870 with 64 bytes of scratch RAM, 64 bytes of executable RAM and up to 4k of mask ROM.

The keen eyed among you will have already spotted another problem. Two segments on the LCD are out, along with two status indicators.

The LCD is a piece of glass with contacts deposited on it in a very thin layer. A rubbery piece with conductive inlays provides contact with the PCB. Held together by a plastic contraption. I gonna need a conductive pen to fix his.
