Amazing it works at all.
I don't remember what project we were working on but it was something that
used (if I remember correctly) 4 of them in the circuit and literally were
ordering them by the truckload.
Different sources, batches, date codes.
I know they were a staple of CMOS projects but seemed to be one of the more
unreliable devices for the era. Many of them seemed to work at first but
then die after repeated power cycles. Similar to light bulbs, usually
worked, power down, power up, no worky.
