There were only 3 machines were ever built. All are in high-end collections. One collector had a tech come and work on some of his games. The unscrupulous tech copied the ROMS without permission- The game was not broken and not one he was supposed to "fix". The owner is reviewing a couple of months of security video to see if he can catch him in the act.
This is the first time that someone has actually had the balls to steal ROMS from a collector.
