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...
Hmm, try saying that 3 times real fast...

Please post the source, if you find one. I have an Atari plotter and a
Commodore plotter (model 1520) that use the same mechanism and the same
pens. What I could _really_ use is a source of the gear that
fits directly on
the X and Y motor shafts. I have tried going to local RC car and model
train shops, but they don't carry gears. This thread has come up
before, but I still don't know how to sit down and accurately determine
the physical characteristics of these gears to the satsifaction of a
mail-order gear vendor. I can mic the shaft, I can count teeth, but the
rest eludes me.
I did buy a handful of plot engines from a surplus house. 80% had
fractured gears. :-(
I wonder if there are enough of us with these plotters to justify having a
batch of replacement gears made somewhere?
