Still don't work. DOH!
I've got LEDs hooked up to port 2 with a 373 latch.

After getting the reading (supposedly, anyways) I'm doing a
MOV P2,A which should display the 8 bit value on port 2. All leds remain zero.
(I'm 100% sure the latch setup works, cause I had it counting in binary on the port earlier today)

Ideas?
