After speaking with several software vendors I’ve learned that win 7 64 bit will not operate a parallel port with any device automation software. So gone is the ttl access needed for so many of our devices! Fortunately there are low cost alternatives. The guys at metamorph recommended this national instruments io controller, which sells for $115 out the door. Not too bad of a deal, and you get a cleaner method of cabling and interface.

Both meta an elements offer Ni drivers, so this should be a simple switch from an old parallel based system.
It’s important to note that this won’t solve the issue of parallel-based communications on devices where they only connect via parallel. It’s important to check with your device manufacturer(s) what options are available before simply chucking your old pc!
