I have two late 70s/early 80s ADM terminals that both power on but have various display issues, and I don't have the know-how to diagnose or repair them. If anybody would want to assist in making at least one good one out of the two, let me know. I'm in Des Moines. The CRTs and power supplies are good but I'm getting garbage or wrong characters on the screen, among other issues.

Thanks!
