I think I'm gonna be kicking myself for passing up on a literal pile of
these for the next 10 years. There was a RadioShack outlet store in
Houston with 100s of packages of these that I could have had for
$0.05-$0.10/ea or maybe $5-10 for the whole lot. I never got around to
picking them up, and the store seems to be gone now. As of 2-3 years or so
ago they still had all kinds of TRS80 parts and supplies. I imagine the
stock was dumped when they closed the store. At least I picked up their
stock of data cassettes and cassette interface cables...

I wonder if there are enough of us with these plotters to justify having a
batch of replacement gears made somewhere?
