Rockwell AIM-65 RS232 interface
The AIM-65 has a fully implemented 20mA TTY interface, but RS232 support is a bit half-hearted. Strangely, it has a fully RS232 compatible receiver, but the transmitter is only TTL, and is also inverted. Hence the reason for constructing this interface board, which also provides convenient LEDs for the serial traffic status, and a nice interface directly to a DB-9 connector. In the olden days, people did produce ready-made interface boards for the AIM-65, but these are long gone now.
