What have I done!

+1 on the voltage spike possibility



Or 3.3V for most modern cards and laptops.....



Maplin still stock some but I'm not sure what bus types for and what voltage data levels.

The PP cards generally are 5v logic.

Sorry, you would need 4 drivers if you have a slaved X axis, I wasn't paying attention to the actuals, just the principles.

What operating system are you using on the PC? Most of these PP cards have very old drivers. They work OK up to XP generally, but no later.

I have got one of the PCI socket (not PCI express) PP cards (dual port) sat in a drawer and several new LPT leads, if you get stuck.

Nick, Maplin used to be good, but it is just a toyshop now. Most of the gear you can get cheaper by up to 2/3 (that's a quarter of the price in pub talk) , though Maplin do take stuff back more readily.

Cheers,
