There are tons of mostly unidentifyable boards with usable parts or we
know what they are and maybe they even work but heck there's a stack
of 100 in the corner with good parts for salvage.
Examples of salvage to me XT clones that were never rare, 386 and 486
boards with salvageable parts. A sharp TV with a dead red drive from
a doitall chip is junk for stripping. Non-salvage items, things I
keep and fix like my uVAX ADVICE as it's an in circuit emulator for
the uVAX chip so it both maybe the last in existance and unusual.
There is junk and not. The junk is there to make the not junk work.
One can have too much junk, rarely!

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.
