Attached parallel board to breakout board can't open up linuxcnc anymore

Well thanks to everyone it looks like I have it working.
After reading up on Parallel port addressing I think I understand it much better. There may be multiple base addresses each of which have 3 bytes per register line. Therefore 24 bits per line. I'm used to programming microcontrollers and haven't used parallel ports for IO.
Apparently according to the manufacturer each of these base addresses may be configured to drive different devices.
Anyhow, I'm getting on and off voltages on my x y axis step pins as I run a program. Looks to me like it should work when I hook up the steppers and drivers to the breakout board.
Appreciate your help.

what does eight topic mean.
What might I use the second parallel port for?

Thanks again
