Thanks for your help
I wasn't very clear. ports b and a aren't used yet, i just left them in there for the future. I calculated that if the timr counts at even 4 mhz, (.250 microseconds), this scaled by 256 should be about 64 microseconds. If the timer goes 256 counts I figured it would take about 16 milliseconds to overflow. At this point, I wanted use the timer0 interrupt overflow to increment a register. So if I increment this register every 16 milliseconds, i realize it will be too fast to see, but if it's an 8 bit register, i should be able to see it fill up (16 milliseconds * 256 = about 4 sec)
Does this make sense?
Thanks for all the help so far. I will try the suggestions given up to this point.
