New Model I/III Diagnostic ROM

Kevin Trojanowski has let me know that Adrian Black has introduced a Model I/III diagnostic ROM to help in troubleshooting Model I/III systems.

The ROM can be downloaded from his Github page.

Paul Thomas Metcalf III mentions that you do not need the adapter board which Adrian mentions if you use a TMS2516 EPROM. Unlike a 2764 or a 27128, the TMS2516 is pin compatible with the ROM socket.
