Hi Pat. Long time since we've heard from you. Glad to hear that you're using EMC2 and that it is working for you.
I've tried a lot of breakouts and the maker you mention is as good as they come. The PMDX-122 is about as low cost as you find for fully isolated. You might get away with just a screw terminal breakout if the stepper drives you're using will handle raw parport output. Note that Gecko drives will NOT work with a 3 volt parport sig. They will work with some PCI parports that put out 5 volt. A search for "parallel port breakout boards" will get you a list of 'em in just about the order I've worked with them. The only one (passive) that I don't see there is a ziplink din rail mount from automation direct. Hope this helps. Good luck. Report back with your progress and (hint) add a page to the wiki with your projects.
