I have made some slight updates to accommodate faster parallel port speeds and encoder velocity estimation via time stamps. But, it has been basically the same product for 14 years. When John Kasunich (and others) developed EMC2, he wrote a VASTLY better driver that flexibly enumerated all the possible devices on the parallel port bus. I never would have had the time to build that enumeration framework as well as he did.
I've been making the Universal Stepper Controller since 2004, and the universal PWM controller since 2006. The "evolution" of Linux has had ZERO effect on the hardware or driver. Yes, the guys who work on rtapi had to do a bunch of work to adapt to different RT systems. The guys who keep the build system working have to deal with a lot of issues to move to new kernels. But, the hardware and drivers are VERY well isolated from most of these changes by the excellent work done by the folks who maintain these parts. And, since there are so many hardware interfaces supported, the code that makes them work shows several examples of how to do things.
