I'd say yes, cuz ISTR the floppy drives actual, at the card edge connector, interface is a step and dir pair of signals. Old full height TPI/Tandon drives had a good sized stepper in them. An rs232 breakout box on the db25 end of the parport cable should get you the signals, and a google search of known floppy drive type, like a teac FD-55 should get you the rest of it, but you'll need both 5 and 12 volts for the drive I believe. As for putting it to doing usefull work, its difficult to beat the $350 for 3 each 262 oz nema 22 motors, and a driver board for them from xylotex.com. They will run the typical small milling machine nicely, using it myself. >Thanks >John > >------------------------------------------------------------------------- >This SF.net email is sponsored by: Splunk Inc. >Still grepping through log files to find problems?
