I don't like option number 1. Actually, I thought option 1 was the "best", but required a bit more code and more testing. Since I've discovered the offending line occurs in ONE and only one place in the whole driver (I think), then conditional compilation of one copy of the source seems like a workable solution. > My big questions... > - Do we know when this changed occurred to actual products in the > marketplace? NO! That's what makes this decision a bit hard. I know some old ISA-bus multi-IO chips needed this, in the DISTANT past. I started this project in 2001, to give you some context! And, once it worked, I have no idea when it might have no longer been needed! And, even WORSE, I have no idea if any CURRENT parport chips still require this. I did check that none of the ones HERE do, but that is not conclusive. > > I also see this as making a large number of cards available for use.

Yes, but there are great improvements in GUIs, trajectory planners, and such that could make life easier. But, a major update, as from 2.4 to 2.7 will almost certainly require updating the PC hardware.
