I am looking for a keyboard that plugs into the serial port. I want to do
reaction time experiments with the Mac. The standard for these experiments
is millisecond timing. The Apple Desk Top bus only communicates with the
keyboard at 60 hz (16.67ms). However, the serial port can run at very,
very fast rates. Hence I'd like to use the serial port as an input device
to get accurate reaction times.
If you have any ideas on how to accomplish this please let me know.
