I am trying to trace out the circuits for the IBM 5364 Driver Card. There are 3 chips labeled R1, R2, and R3. They have the trademark AB in a circle which I think is Allen Bradley.
R1 is 316E221331 with 8501 under the number. R2 and R3 are labeled 314A822 or possibly 314AB22 with the number 8502 to the right. Checking Mouser all the other chips are still available but some with 6 weeks or more lead time. I have two working cards but would like to document as much as I can as a learning project.
I know I do not have the expertise to complete a project like this but hope to learn from just trying. I would hope someone could suggest alternates that may work.
I have attached a picture of the front of the card.
Thanks for any help.
