I was actually working on the casino floor for a year and configured, repaired, diagnosed, and twiddled with these machines all day. It was a terrible job, but gave me something to do while hunting for my next IT adventure.
Other interesting observations: the machines based on Windows XP Embedded crashed all the time, the Linux ones were fine.
The Linux ones from several mfrs used APNG for the slot machine graphics. This was my first exposure to animated PNGs in the wild. (~2007)
The Linux machines loaded a kernel module at boot that was supposed to prevent/detect tampering with memory. Some also loaded their own audio driver stack which surprised me: wasn't ALSA or OSS. Very odd, specialized little machines. (Many were Pentium 3 with totally custom motherboards due to strange peripherals)
Progressives cannot legally be removed from operation until someone hits the jackpot. (at least in my state)
