The spare parts box that was part of a tek4052 deal
has several Tektronix spe
cific 40 pins DIL, date around 1973
These are
156-0235-00 C8684
156-0238-00 C1840
156-0236-00 C1841
156-0243-00 C1842
also a MOS MCS1020
Anyone know what these were from ( not the 4052), maybe a tek 31 ?
They are almost certainly ROM chips. I can't think of any other Tek
sourced digital chips except ROMs in the circuit diagrams I've
studied. I think Tek did make a fair number of their own analog
chips in that time frame, though.
