Just don't scrap the DZ11s, make them available to
people who want to
scrounge bus transceiver chips from them.
Bus transceiver chips for Q-bus and Unibus are *not* common as dirt
and more than a few of us have scratched our heads on how to create
new compatible circuits. Meanwhile, the scroungers taught me that
it might be easier to scrounge the bus transceiver chips off of dead
or readily available boards.
I am talking from a purely business perspective.
The hobby side of things works on a different set of rules. I have a
large bunch of boards with interesting or rare chips that I am saving
for parts scrounging, even with gold edge fingers and things removed.
Sometimes, I will even cut down a board so the interesting or rare
chips are left for removal when needed, but most of the rest has gone
to the shredder.
