I made a couple of the DEC LA-36 RS232 interface boards by removing the
couple of components from the baord, putting the bare board on a piece of
diazo film, and making trial exposures until I had a piece of diazo film
that I could use directly to image new boards with. I would guess any good
photo house could do a similar operation using silver film and come up with
usable artwork. Shooting a dot pattern of the holes would give a template
for NC drilling the boards.
Hey, neat! I have my ET-3400 still, and I also
didn't know one of
those existed. If you find a second one, I would be much appreciative
if you would send me a pointer...
Either that, or run the PCB thru a decent scanner/copier to see if a good
enough image could be had to run a few boards? (I've got an ET-3400 too!)
