Me, too; and I think they are on the funet archive (wherever it ended up

Technologies fab; they tended to go for chip-level solutions as opposed
to the things that Apple did in those days (standard parts, essentially).
The controller
in the C= 1520 is a 6500-family masked-programmed
controller and only implemented the C= IEC bus...
Yes, that's one of the odd ones (I have the schematic for the 1520
somewhere). I am wondering aobut making lantern pinions the right
size. Yes, the
tooth profile on the meshing gear in the plotter would be wrong, but
would it matter? And a lantern pinion is a lot easier to make than the
original type.
I am unfamiliar with a lantern pinion... what is that?
