What an interesting device, I've never heard of such a thing.
How does it realize full-spectrum color if it uses primary color wheels?
Maybe by varying exposure time of each color?

Folks,
Trying to reduce the weight in my loft and I would like to donate my HP
Photoplotter to a good home.
. Photos of the plotter and some sample plots are on my OneDrive here:-

It has both serial and IEEE interfaces and uses HPGL like the GP and Roland
pen plotters.
The plots on there are the samples built into the plotter taken on a Fuji
XE-1 digital camera and are cropped because the Fuji does not have a full
frame sensor.
The tube is actually a white tube and the colours are generated by rotating
colour filters.
Its powered by a 68000 and you can see the various boards in the pictures.
