Just compiled it as is.

And it works with no problem as seen in the simulation (attached).

Actually I see you have a pull-up on pin 1 and also have pin 7 tied low.

I don't see how pin 7 can be any problem for me but looking at the PCB I notice it doesn't have the pull-up on pin 1.

Existing (pre-programmed) 16F883's I have on my bench are working fine when inserted into this PCB so I have reservations thinking that's the problem at hand.

Thanks for your responses everyone.
