One thing to point out as well, for arcade operators the machine had a couple of benefits due to it's cartridge based system. When a machine has been on site for a while, it's takings tend to drop as players get bored of the game, so as an operator you are continually having to buy new titles and shuffle games around sites. So you would have to get a van + man to turn up at site 1, unload new machine, swap them over and drag the old machine back into the van. With a cartridge based system you could have your tech turn up in a car and have a new game installed in less than 20 minutes. The idea was the same for JAMMA based cabinets, but Neo Geo just made it slightly easier.
