Yea,
I did quite a few board designs with Bishop Graphics. Initially did the black crape tape then moved on the the ruby tape. Still got a box of the old stuff, but the adhesive is all dead. I had a fairly good setup, consisting of a light table, precision .050 grid film with pin tabs for aligning the layers. Would do a pad only layer than tape up a top and bottom, trace only sheets. I think it cost me about $12 to get it reduced 2:1 with a negative for each side. I was using positive resist so I would make my own contact copies for working film.
The hardest part was getting the photo house to make sure they got the taped masters oriented correctly on the camera so the final film emulsion would be against the board. I finally had to put a big note across the master tapeup with the words "THIS SIDE TOWARDS LENSE"
LOL Oh, so many hours so long ago. Now everyting is so small and my eyes so bad.
