Our classroom time on it was pretty limited - a week or two, at most. I vaguely recall that it was used to teach a smattering of machine language and digital circuit fault analysis & troubleshooting. That's about all I remember, and unfortunately I lost most of the tech pubs I had kept from those days in a move several years ago. If anyone else on the list attended tech school in Millington during that era, perhaps you can answer a question I've wondered about for a while. The Navy was experimenting with computer graded programmed instruction in the early 80s, and the machine that processed the Scantron forms would print out a line or two of remedial info or "attaboys" on each test report. Unfortunately, we never did get to see "Jim-Jim", the machine which processed our grades. Does anyone know what kind of hardware Jim-Jim was? -Rick Kaumeier
