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.

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?

I haven't either, but when I saw the sample output it rang a bell. At DEC, in the
1970s, we would prepare presentation material for customer talks such as DECUS sessions by
sending manuscripts to a nearby company named "Genigraphics" which would send
back images looking much like the samples, on 35 mm slides. We'd put those in a
projector and use them with the talk. This was long before Powerpoint or PC projectors.

Well that’s what it says in the manual, but sure how it achieves this. The samples were
taken by opening the shutter, running the demo and then closing the shutter but as you can
see the sample palette comes out fine.
I don't know if it varies the brightness or the plot speed....

Hi Dave,
Did this go? If not, I'd be interested. I'm located in Hebden Bridge, so
could drive over to collect.
Best,
Andrew
