eprom?

EPROM? Are you still talking about VPW, or casino machines?

IGT supplies a good majority(monopoly?) of the casinos with VP and slots. RNG chips are onboard but it's up to the slot tech to adjust paybacks and monitor the RNG for proper function. Gaming control boards also make sure things stay on the up and up. 
 
I've always wondered whether game chips are ordered with specific paytables, or if they're set in the casino.  Is that true, Ed?  Certainly cheaper to allow paytables to be set by the casino instead of having to order new chips each time.  If set by the casino, you'd think that now and again they'd make an "oopsie" and have a RF set to 40,000 or something like that.  Maybe the software is smart enough to catch that stuff.

I believe there are a wide variety of pay tables for the casino to choose from, but likely not full customization. I'm sure they have details such as expected return, etc for each.

CD, from what I gathered after reading a couple of articles,one in LV Advisor and another in LV Review-Journal, they are allowed to set paybacks according to their schedules and are also allowed to set some to be"loose" although the NGCB doesn't like to use that term loose but rather"generous"(whats the stinking difference whether  its loose or generous?) One LV casino had advertised loosest slots and the NGCB made them cease the ads immediately and fined them 50K for using that term. Good to know some are actually loose!

I'm not sure either.  I have heard that there is supposedly a thirty day process a casino is supposed to go through in Vegas when changing paytables.  All very formal with the gaming commission involved.I've seen a lot of "service people" pulling up maintenance screens but the ones I've talked to would not disclose much if anything about what they were capable of doing with those screens.  No doubt, many of them were diagnostic.

They aren't allowed to tinker with the RNG chip and matter of factly, it's somewhat sealed in place so the Gaming inspectors can tell if its been tampered with. Only the paybacks are adjusted. GCB can pull a surprise inspection to make sure everything is jake.

i guess the eproms can be manipulatd with ultraviolet light,but that may be in home vpw games only.

I think the innards of the machines are well protected.  I saw a documentary once that showed a tester using a taser on a machine while it was running, and it didn't miss a beat.

How about strobe lights?
