Anyone ever heard of this? It reminds me of the Quake: Tournament Edition cab which I foolishly passed up many years ago when it was on sale in the mall for $500.
Here is an excerpt from Next Generation magazine September 1997.

....a startup company out of Philadelphia called Network Entertainment Game Systems (NEGS). They are starting with existing proven hits from the home game market - figuring that millions of kids don't have computers at home and would love to play these hot titles, but never had a chance before. Later on, the company intends to offer brand-new titles, designed specifically to debut on their arcade platform. They also say their system will offer the capability to link games into a network via modem for tournament play.
Specs include 180Mhz processors, 32MB RAM and advanced 3D accelerator cards, all upgradable. Prime Target by MacSoft is its first game; it's a first-person 3D game in which the player gets a chance to save the government from a violent takeover. There are 25 levels, nine different weapons, and the usual hordes of villains who come looking for you. It's been testing in a Philadelphia-area Champions Arcade for some time and should be appearing in more arcades by the time this is published.
