I think our salvage department works like a dog pound - if no one wants it and puts up a few bucks for adoption, they crush it! Seriously folks, if anyone wants it for spare parts, give me a call and I will get them in touch with the right people here. And for some real process control nostalgia, has anyone out there ever programmed a GE-312? This was the only machine I ever knew that had backup for the machine through the memory. An AC motor turned the drum memory; torque was sent through the drum to turn a DC generator mounted below. The generator charged batteries and acted as the drum motor if the power failed. Since it was a synchronous machine, minor speed variations did not hurt. I still have the power supply for one of these. It took six of us to lift it out of the cabinet. Of course this was also the only computer I have ever seen with crane hooks attached to each cabinet. Wow, a multiton 32K word (20 bit) machine with 512 point analog I/O (16 bit) with a typical execution of 10 instructions per millisecond. And to think I did direct digital control with this machine. The power supply makes a nice arc welder! Barry L. Ornitz Eastman Chemicals Division Research Kingsport, TN 37662 615/229-4904
