 		 #3763 - RE: Port 2 input buffer
Provided you are using a chip with internal rom and no external memory then you can just use p0,p2 as I/O.

I've currently got an at89c51 chip running with epson compatible printer port and lcd display with no extra chips and neither of which share pins on the processor.
