I used to own one of these. My Sunday school teacher gave it to me. I didn't have the resources of the internet at the time, didn't really think of it as a computer. So I tore it down and examined it over a period of a year or so. Thought I had a fortune in gold (gold was about $600 an once in the early 80's). It was all plate. I think I have a few of the boards somewhere, the counter and a few other things. I loaded the chassis up in a 1974 Torino and scrapped the magnesium for a few bucks, junk yard guy didn't believe me when I told him what it was (he asked).
