I have some circuit boards out of a 1980s Intergraph photoplotter, and I
could probably manage to get the laser and such from it as well. When it
was operational, it was also used to make PCB artwork.

I'd be interested in seeing some pictures of your photoplotter, if you have
a chance. Now with the idea of direct toner transfer with modern laser
printers, I can see bringing a darkroom into it as being a bit of a hassle.
But still, quite cool.
