The US Letter size of folded Versatec paper came in a cardboard box that
was really good for compartmentalizing small stuff and stacking for
storage! I used to scrounge around the waste containers for empty, used
boxes. Still have many in use.

Yes, there were a number of Versatec models for

paper sizes and pixel density.
Does anyone else have one in their collection?
I have an ICL-badged V80 which has a GPIB interface to link it to a
PERQ. I also have the schematics, etc for the plain V80 but nothing on
the GPIB interface (ether user or service data). IIRC the V80 is based
round a Texas 16-bit microprocessor with some AM2900-series sequencers
and ROMs to control the electrode timing.
As Jon said in the bit I deleted, there's a 'nib electrode' under the
paper and a segmented backing electrode above it. The charge image is
built up on the paper, then the toner is flowed over it and the carbon
(I assume) particles adhere to the charged bits. No drying heater in
mine.
