    VT320 problems solved

    Replacing the driver and DUART ICs fixed the printer port but not the DEC423 port. With the terminal connected to the computer I discovered that if push the plug in and up (and hold it in place) it makes connection and the terminal works as it should. I then did some connectivity checks with...
