Dell Octoplex GX620 parallel port issues

I don't use a dell pc for parport application's. No window's and no linux for ltp1 and dell.
Quicker is to grap another pc brand.

I use a LOT of Dell Optiplex computers on a lot of machines with parallel port or Mesa 5i25/6i25.
I do not think i ever used a 620. All of them are 7xx series.

My favo is like the HP Compaq 6000 PRO. I tried a Dell once without succes. Maybe it is a sad story... :whistle:

It might be worth looking at a Mesa 5i25 or 6i25 instead of the parport. The form factor is the same as a PCI(e) parallel port, but with step generation done on-board the step rate and accuracy is orders of magnitude better. (no exaggeration, 20kHz v 10MHz max step rate)
