twin staged,
The port standards have changed over time. Check for differences on how the cards go into the motherboard. May not even fit.....sorry but just don't remember the history.Ā Yes there are differences between cards, like output volatgesĀ etc.. Additionaly the signal quality can be crap.......thus you end up with stepper not running right.
Make sure you get a return policy with purchase of the card.

BTW i had a hell of a time with a dell and somebody sent me a driver for the card and it worked. The drivers that came with the one card where garbage. Point is, the one $10 card wasn't worth the space it took in the gabage can!
