The manual/documentation I have gives a procedure you can follow (manually
flipping the switches all the way) which is a self-test. Following the
procedure you can check if your 8800b is working correctly. Using this
procedure I tracked down several problems (loose wires to fron panel) but
still have the address light problem.
I'll track down the procedure and explain further, if there is any interest.
I appreciate the comments about the alignment problem, and can see how
basically I should be concentrating on the Altair first. So thats what I'll
do.
More soon.
