    so that serial board will arrive in the mail tomorrow https://www.ebay.com/itm/VINTAGE-COM...72.m2749.l2649.
    I realize now that this rs-232 device is card-edge so I'm going to need to buy/build an adapter. So as I posted earlier in the thread I am already working on making this : http://biosrhythm.com/?p=1136

    Will this suffice to connect a standard rs-232 device? (also the rs-232 ttl adapter I bought from China so it will be at least another week and a half before I get it in.)

    On a similar note I only have the one ieee-488 card - edge to hpib adapter for my pet. Does anyone know a source I can order another one?

    How about a 16450 UART?

    In the very early 80's, I used an Anchor Automation 300 BAUD modem made for the PET that hooked up to the PET User Port. It came with a program that contained both BASIC and Assembly routines on Cassette.


    One loaded an ran the program, and then could type characters that were sent, and receive data on the screen at 300 BAUD.


    I needed the capability to remotely log into a University IBM mainframe to run a program called General Purpose Simulation System (GPSS) for an Engineering Statistics class.


    Of course the data display was awful on the 40 character screen, so I had to hook up my Heathkit 132 column serial printer to the RX signal that the MODEM was sending to the PET on the User Port and kludge it into the Printer receiver circuit (as it was a TTL level), but then had a nice hardcopy output of my listings and program output. I aced the class without ever waiting in line for a computer terminal.

    You just gave me a really good use for the wide format PET printer that I have.
