hard to get but there is a place in Arizona that sells various hard to get pens.
Does that plotter take the pre-7475-style pens with the two little
plastic "ears" on the sides, that you insert and turn to lock? I have a
7015B that takes those, and I'm looking for pens. If you think this
place would have those, would you please send me their contact information?
It looks like the other guys beat me to it. That is
the place I bought my pens from.
They seem to have pens for just about anything.
Excellent. Thanks everyone! I'm going to use this plotter to help a
local friend understand R/C time constants. (he's a "hands on" guy like
me, we can understand things much more deeply if we see them in action),
then it will live with my analog computers.
