PIC16F84A Tachometer LED routine

Hi, Santa ( de bois )
1) Just the usual gag with PORTA.4 ...
Did you place an external pullup resistor or something to drive the pin to HIGH state ???

Only applies when using PortA.4 as an output...

2) - I don't think the Simulator cares about HS or XT :-)

Arg! Simulators!
