I bought 12 of the machines. I got a full cross-section of conversions including a (former) Galaxian, Ms. Pacman, Dig Dug X 2, Joust X 2, Defender, Off-Road, green Taito caband Zookeeper.
The only game matching inside and out is Off-Road and it loks complete. Otherwise there are 2 oroginal cabs with non-originals games and 7 conversions. I'm hoping to get most all of them back to original. I know that sounds like a major feet, but I've got time.
