I'm using EMC and was in need of help to clear up how to wire it up. The step is pin 20 and the direction is pin 18 on the edge connector of the floppy drive. How and why do I need the resisters? The floppy logic is pull low for on. Can I just power up the floppy controller and short pin 20 (step) to 19 (ground) to see it step once and verify that it is indeed the correct pin? Or do I need a resistor to prevent too much current flow? Thanks John ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
