In the spirit of this conversation is worth noting that a separate computer to run the machine is a must. I have 2 in fact, old Dell cost me 30eur from a local boot sale and has win xp installed and is running fine.

Another thing is that i have 2 BOBs , the second one for closed loop and some extra inputs and outputs and it took me a lot of time to fiddle with printer port cards, PC BIOS and how to make them both work and in which mode each. Its worth researching before, about the exact modes needed to run the board you have or the integrated port, cause some computers LPT boards or LPT cards will NOT work due to lack of a certain mode.
