Vintage electronic lampshade
I was in a restaurant this evening and this lampshade caught my eye. The first photo is poor because it was rather dark (ironic, considering the subject) but it's a square lampshade of which two sides are made of old PCBs! I thought the terminal block on the ceiling connected to the fabric-covered iron flex was rather fetching, too.
Naturally I had to take a close-up photo (with flash this time) for later examination. The board seems to be covered mostly with UCY7400 series logic - Polish-manufactured versions of the TI 7400 series. Some date codes in 1978 are visible. It looks computer-related to me, given the big edge connector at the bottom and (not visible in the photo) a crystal in the top left. I wonder what its history is? The food was good, too... Chris

Re: Vintage electronic lampshade
I like the neatly done mod wiring in the closeup. It took me a while (some 20 years ago) to realise that the useful sticky dots holding the wires in place were just a bit of hotmelt gluestick dabbed on with a soldering iron!

Re: Vintage electronic lampshade
I have a set of coasters stamped from unpopulated PCBs. It was a gift from Mentec after I and some colleagues ran some tests on a prototype of their 'PDP-11' CPU board.

Re: Vintage electronic lampshade
That's a quaintly relaxed density there- I'd have been laughed at if I hadn't got 50% more ICs in!

Re: Vintage electronic lampshade
Doing mods wires with glue was an art. We used candle wax before that and the delightful wire wrapping tool

Re: Vintage electronic lampshade
Yes, there was fine line between securing the wire neatly and melting the insulation which could be a problem with multiple wires and didn't look good.
