could probably manage to get the laser and such from it as well. When it

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.

board artwork. It does 1000 x 1000 DPI via a raster
process, wrapping the
film around a drum. After moving all the conversion software over to
Linux, it occurred to me that it might not be hard to convert some raw
pixel image format produced by one of the PostScript converters to the
format for my photoplotter. it was about a one hour exercise to get it
working!
Not exactly a one button operation to get images, what with all the
darkroom processing, but I might use it some day. I mostly use it now to
make solder stencils for board manufacturing.
