Mine had never been tampered with until I was trying to find that lock (which I didn't even know was there until I finally broke a pin off the cover). So apparently you were only allowed to 'service' or 'modify' the machine a very limited number of times before the Yakuza or whoever inspected them would. Once you break one, you have to replace it but there's only a few. Each one has numbered, tethered, one-time use 'pins' that secure covers which restrict access to components, and messing with them is immediately apparent.

To your point tho: there are several tamper-evident plastic barriers throughout the assemblies.

It's a stout metal unit that simply preventing the cover from being removed, with no electrical connection or mechanical interface to any component on the board. I don't doubt that may be the case with some types of gambling devices.īut studying this one, the lock appears to only be a physical barrier to the board cover. The lock would be easier to replace (but why bother if it doesn't help). I don't want to even attempt removing the sticker tags that are obscuring it, because they're self-destruct tamper-proof and part of this machine's mystique. Yet I'd hate to bust the lock to extract the one part of the CPU I can't see only to find out there's nothing there. but I can't find one ANYWHERE that's visible. Seems they must have saved settings (time / date / menu options / etc) somehow. in other words, does anyone know if these things have batteries on the CPU board? So the questions I have are probably obvious and hopefully simple to someone here:ġ) Can this type of lock be drilled like a traditional one, or is this style of lock specifically tamper-proof from that?Ģ) Does it even matter in this case. I think this must use the type of keys which have dimples instead of sawteeth, but I don't have any and regardless there's no way for me to know which key fits this lock. And to remove the CPU board at all, you have to unlock a hasp buried beneath a tamper-proof security tag.Īnyway, once I found the lock. I can't tell if the CPU has a battery backup because it's encased in a clear plastic security housing, and part of the board is obscured by gaming and warranty tags in the way. It works great and has all sorts of weird hidden features and sub-games and the like which my kids have had a blast trying to figure out, but it doesn't save settings. Picked up a cool Japanese slot machine ('Pachislo') for a song a couple weeks ago.
