NWA auctions (GP-4, SEL 32)

[William Maddox]

This looks like a GP-4, though I am suspicious that parts of it have been modernized.   The GP-4 had a drum memory.

Someone should grab the SEL machines:

There are a few 3C cards in the pallets of parts, and a few can be seen in the 7th photo here:

Computer Control Company machines (e.g. DDP-124) were widely used in simulators in the mid/late 1960s, when many simulators for aircraft of that vintage were built.
The computer itself is nowhere in sight, however.  Probably, all that remains are specialized simulator interfaces, with the PC in the last photo doing the computing.  :(
