I can make little LEDs glow out my printer port with an
external assembler routine. What I want to do is receive data from an outside source (OK the ignition off of my old Ford truck) I know the circuitry that need, but I need to know what pins to use on the printer port and how do I suck that data in. Please E-mail me as I don't get here often. By the way, is there a good Q&A mailing list out there for this wacked out kind of stuff.
