Robert and I ran across a dumpster brimming with old equipment that the CMU physics department had thrown out. This was ancient stuff, mostly from the 70's and 80's - signal generators, ADCs, etc. One of the more interesting pieces was a mini-fridge-sized Fabritek Model 1070 Signal Averager (c. 1970). It was too big to keep in the lab in one piece, so we gutted it, extracting 512 bytes of magnetic core memory and a bunch of old school electronics boards. I turned the latter into a desk lamp. The boards are populated with a wonderful variety of components (by hand I presume) and are translucent, allowing traces on both sides to be seen.
