I took some photos of the box and put em on my homepage (see
http://www.baigar.de/TornadoComputerUnit/) maybe someone is interested...
The label of the box reads "Programmer electronic Control", manufactured by Marconi Avionics with part number 51-019-02, NSN1680-99-652-3410. There are lots of boards in it. Among them are boards dealing with driving the core memory:
(1) Driver Board, 1680-99-646-6754 and
(2) Data Board, 1680-99-646-6755.
The core memory itself consists of a sandwich of two boards by GEC-Computers. The capacity must be around 64k Bits:
(3) Core Memory, 5841-99-652-3386.
Thanks, Erik.
And more boards beeing something like a processor assembled from discrete components.
