I finally found some docs so that I can make this thing work on a PC. If you don't know what it is, take a look:

Details are here: http://brutman.com/IBM_LPFK/IBM_LPFK.html . The only thing I'm worrying about is the serial port on the PCjr .. it's not going to be happy at 9600, and this thing won't do anything but 9600. I might be trying to put a 16550 class UART on the Jr to get some buffering on the chip to compensate for the poor system.

(Has anybody tried replacing the stock 8250 with a 16550?)
