Strange what you find in the back of your garage.

Never heard of the IYONIX Gary.

Strange what we keep.

Here's a Casio PB-100 which I used back towards the end of th 80's. You could write programs for it in Basic. I wrote one to quickly attain the ships stability status. It was excellent. Just ordered some new batteries for it to see if it still works.
