Drew, 
   I have already figured out how to use the Printer BUSY pins 21 and 25 and
the barcode data pin as 1 bit input ports when crossed with the Printer DATA
pins (3,5,7,9,11,13,15,17, and GND).  If you would like a copy of the program
leave message.  If I can solve the software timing, I can use any input pin for
the 1 bit port need and 1 of the DATA lines for the output port.  I left a copy
of the port reader with Rick but it only reads BUSY25 and BARCODE DATA pins.
