Me too. I've got piles of obscure boards that I'd like to get going again
sometime. Most have no real practical function, but are part of the
history of computing/electronics.
About the only thing I'll raid for parts are no-name clone PC
motherboards and cards.. And those are not a good source of standard TTL,
alas.
There are plenty of junk boards that have no particular useful function.
I've got a bunch of ISA cards that I salvaged. All were old models of a
gizmo that appeared to a PC as a monochrome adapter, but which translated
the CPU writes to video memory to serial codes to a VT-220 type terminal.
Now that sounds unusual enough to be very interesting. Put it this way,
if I had something like that I'd be trying to track down a dump of that
missing ROM. I would not be raiding it for parts.
