Yes, I was thinking of the very old DOS games which were single player, or you used a null modem cable.

I have never really studied the hybrid games in any detail (I mean those that use DOS and Windows) so I am not sure how much of the networked ones took place on the server and how much on the local machine.

I have looked a bit more at this offering and the new version DOES SUPPORT multiprocessors and multithreading.

It looks like an update to enable modern hardware and operating systems...............worth a look if you are into older games.

I notice that they offer a 30 day trial as well
