Regarding error codes in the 5071A. This "feature" was an afterthought. All of us hardware designers brought out test points that were easy to implement and then the microcontroller polled them and software was written to give error reports. We did what was easy on already finished board designs; not what would be optimum if designing from the ground up. If you can repair a 5071 based on the error code, consider yourself lucky.
It is analogous to that old gag about the drunk who is crawling around under the only street light in the neighborhood. A bystander asks him what he is doing and he says he is searching for his wallet that he lost. The bystander asks him where he lost it and he says "on the next block". The bystander asks him why search here and he says this is the only place with light.
