Got: books!
Got them from a retired physicist who ran his own software company from the mainframe era of the 70s up until the early 2010s

Got: an oscilloscope card for IBM compatibles!
This thing is ancient, the specs are miserable and all it is, is this Analog Devices ADC with addressing logic and a few AD711 OP amps as a front end. But it's pretty damn cool.
This is what I got in exchange for the Philips scope.

Fixed: Philips PM 3355 hybrid analog/digital oscilloscope. Data acquisition board suffered damage from leaking capacitors, including a broken trace that took some diagnosis and circuit analysis to find. Oh and the power supply was bad, too. Oscillating frequency pulled into the audible range by a bad RIFA, that did not blow.
