Can I ask why are you going to use a peeCee for this? Kind of an overkill, and slightly difficult aunless you plan to use a laptop. Anyway, you might approach this in several ways. 1. Use a serial port and look for the INT line to toggle. 2. Use the parallel port (some discussion was done on this already, and a magazine had an article (RE I think) on doing this as well. 3. Use a small single board computer, like micromints or such. It would be pretty easy to writea small program for the 8051 to just read in the pulses and do some quick calculations on it. I just think a PC would be a major overkill for this (granted a system would only run about $250 running on AC, adding about $100 for an inverter if mobile). -- Evans & Sutherland Computer Corp.
