This is a update on the Pulse Width Monitor that Steve Ravet posted several years ago.
This one uses a built in module to measure the on and off times of pulses on pin-13 (RC2).
There are no interupts to handle, it just counts clock pulses on a logic one or zero on pin 13.
In this case the 4 mhz is 1 mhz internally (instruction cycles). The display is a 2 line x 40 character
Hatachi 44780 type that is widely available, a smaller display can be used, a 2x 20 display would work 
as well.

I've tested this on my LT1 and it seems to work well see attached jpeg, with the monitor in action.
