Show us your junk!

neuromodulator

I love junk, specially when it can be fully restored, has interesting parts or uses interesting technology. Most of the junk I get, comes from the university, its dumped because its either too old or it doesn't work anymore. I'll start this thread by showing one of my latest junk acquisitions:

This is an autotransformer made by a company called "The Superior Electric Co" from Bristol, Connecticut. It was apparently build in the 60s (according to what I found in the net) and supports a max of 1.2 kva. The autotransformer works as expected but of course it shows its age, the rubber cable is not in the best condition and so isn't its paint. In the future I may repaint it and replace the cable but for now its good enough as it is.

 

Have you also found nice junk? Show us!

    Here is the first processor controlled instrument I designed. Intel 8748, code hand assembled on paper and entered into Intel desktop dev system by hand in hex.

    Not really junk, but not very useful now.

    PCB date is 1982.

     

    The design was done for Post Office/BT as a replacement for their own design which used a few transistors and several relays.

    They never bought any but it got them interested and we developed several quite nice test instruments for them.

    The nicest was the ..356 which used six or 8 (can't remember) Xilinx XC2064 FPGAs.
