I hit the recycler today and found some cool looking old circuit boards from an old
oscilloscope. One has Copyright 1969 Tektronix, inc and is a readout system board and a
smaller board with just a part number. What caught my eye was the hand laid traces (curvy
pre CAD), and the chips on it all had gold/copper leads and were socketed. Most of the
chips are Tektronics made (there is a ti sn7402n), I assume the chips are just logic
chips.
Are they worth anything?
