Hi Tony:
Being a Model Railroad nut, in addition to messing with computers. And
since the model railroad hobby quite often gets int 'gearing' problems,
take a look here. No guaranty http://www.nwsl.com/

The Commodore one was the 1520 AFIAK (I have the service manual
upstairs...), but the same mechanism (with different electronics) went
into the CGP115 from Tandy, the Oric printer, and probably a few others.
There was a narrower (2", maybe a little more) that went onto the Sharp
PC1500 calculator.
There's a design fault IMHO. The plastic pinion on the stepper motor
spindle is force-fitted, and it cracks and slips. _All_ the plotters I
have like this have suffered from this on at least one axis. Alas the
parts list for the mechanism doesn't list the pinion separately, only
with the motor. And I've not (yet) found a supplier of replacements.
Sometimes enlarging the central hole so that it's a sliding fit on the
spindle with the crack closed and using iso-cyano acrylic
hydro-copolymerising adhesive to fix it will work.
Ever see the 'Plotter' they had? The paper was a roll like is used in cash
registers, and it had 4 miniature ball point pens. Now that was a lame
printer.
Is that the same plotter that Radio Shack sold? I think it was a
CGP-115? I added NiCad batterie sto one and interfaced it to my HP-41
using the HP-IL, pretty neat. I think I still have one around here somewhere.
