I have started to interface it to a CP/M computer. Haven't had time to get it working yet. The actual hardware interface is easy -- an opto-isolater, a few diodes and resistors. You need 5vdc out, running at 31.25 kilobaud (strange number, eh?). Same for input. @hnij@ John Labovitz hnij%oz@mit-mc.arpa -------
