Hi,

I have recently made a clock program in assembler.  I have tested it
with the SIM and the stopwatch, and it is about 0.000041 seconds out
every 2 seconds.  When i download it onto the PIC though, it is a
visible amount out - I have it next to an accurate clock here, and it
can get as far out as half a second every 2 minutes.  I am using the
16F87's internal oscillator, running at 8MHz.  I have checked the
datasheet for the 16F87, and it says the internal oscillator is +- 1%
accurate, I think, at 25 degrees C.  I think something must be very
wrong for it go get that far out.
