I'm tracking down some info here for a researcher who wants to use his 
Mac IIsi as a timer and counter. One external device he would like to 
hook up is an infra-red beam "people counter".

It may be a case of ludicrous overkill to get an A/D board to do this 
but does anyone have a better way? How about going thru the ADB port 
somehow. I assume there are no "off the shelf" solutions to this guy's 
problem and he may end up having to piecemeal the thing together, but it 
may be prohibitive in cost and/or time. Any suggestions? - Ross
