You can get new pens, as in actually new, not new old stock, from a german medical supplies company, and you can get new motor pinion gears by 3d printing believe it or not. I have also found the gear in brass, from a r/c helicopter company, but those appear to be no longer manufactured, just existing stock.
The pens and gears are the same as for the CGP-115 and a bunch of other plotters that all used the same engine. The paper size is different though. http://tandy.wiki/CGP-115 On Tue, Aug 7, 2018 at 10:08 PM Jim Toth <jt...@localnet.com> wrote: > You can still purchase PC-2 printer pens? Excellent.
