AP 120B

While mine is attached to the data general, FPS made their FPU's able to connect to many different systems, not just DG. I believe I may have extensive docs on this unit. If not, they are still in transit to me from the prior owner. This thing is fairly heavy. It obviously sucks serious amps too. The power cable for it is as big around as my wrist and very non-110-ish (it looks like some mainframe plugs I've seen). I opened the side cover and each card has similar (if not the same) numbers as the unit on ebay. One thing that strikes me about the unit is the density of circuitry. There appears to be very little circulation space between the cards or around them. The entire box is stuffed with ttl from corner to corner with little open space anywhere. Not sure how they kept it from burning up. Perhaps related, perhaps not... my college had a 3rd party floating point processor attached to the IBM 4341. It was a large floor standing blue & white unit. I am fairly sure it said "Floating Point Systems" on it too. Jay West
