I was given these in a lot of stuff I picked up last year. They are marked GRI Computer Corp. 1969.
Obviously they're in pretty rough condition. Sorry for the dark pictures. I didn't realize they were this hard to see until looking at them on my PC. If someone wants more detailed pics, I can take better ones.
What did they most likely come out of? Are these boards useful to anyone? I'm trying to scale back my horde of vintage stuff that I can't use, so that I only have stuff around that can actually be used. As much as it pains me to get rid of nearly 50 year old computer components, if these aren't useful or worth anything they've got to go... they're huge and feel pretty brittle!
