Now that my MIP from sim world is on it's way just wondering if someone can tell me what card do i need to get i order to get all the switches and knows to work on this MIP.

I was looking at OC and Phidgets but getting a bit confused. I see OC has parallel port connects.

and also i dont know how many card to get to get the full MIP to work. I presume with all these card, the software does come with it or that need to be bought separately.

thanks for reading.
