A lot of things had circuit diagrams then, I did chip level repairs on Kaypro clones, and CP/M machines at the time, and it was all TTL off the shelf chips. You could follow the signals through the diagram with a logic probe, clip out the broken gates, clean the board, and pop in a new one, it was very satisfying.
