Note the 'TESTER' setting which can be selected using the DIP switches. Presumably John has access to some form of documentation explaining this functionality.

Hi Alan,
Yes, in test mode all seems to be functioning. I have sorted out the lower case issue - had the 6520 and 6522 in the wrong sockets! However, I am still getting the random character screen so it must be a dodgy connection somewhere. I shall start with my replaced socket. Thank you.
