Thanks for pointing that out. That's good to know.

Yes Tom, RT has very good latency for Mesa boards, and can also do parallel port or direct motor drive control, on newish PC's. RTAI is better for older PC's.
I have RT on two core2duo PC's and the latency is low enough to use parallel comfortably, one of them has another add on PCI parallel card and a Mesa 6i25 in it, so it total it has 4 D25 connectors on the back.
