satellites due to its reliability

I am still debugging the microwriter, and have not got very far. I have
an RCA user manual on the processor which seems quite comprehensive, I
am
asusming it's accurate.
I thought it was a defective 1802 chip, but another one pulled from an
old board shows identical behaviour (right down to locking up after
typing 8 characters on the microwriter keyboard). I can't believe 2
have
failed in exactly the same way. Unless of course this is a well-known
problem.
Any thoughts?
