Subject: Strange Versatec Plotter question
A very long time ago, I used to support three Versatec plotters. We'd have to
use a clear liquid to clean them up. It wasn't Isopropyl Alcohol. Does
anyone happen to know what it might have been?

I think the clear dispersant is a isoparafine, probably the deodorized
kerosine used for camp stoves would do. I still have a 3436 400 DPI color
plotter in the corner of the junk room at work. We used to use it for PCB
plots, I built my own PC interface card with FIFO and output handshaking
state machine logic for it many years ago. Now it just sits. I'm to lazy get
rid if its 600? pound carcass. BTW it uses a TMS 9900 derivative for
control.
