Picked up a cool Japanese slot machine ("Pachislo") for a song a couple weeks ago. 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. 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. And to remove the CPU board at all, you have to unlock a hasp buried beneath a tamper-proof security tag.
Anyway, once I found the lock... it's a bit different:
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. So the questions I have are probably obvious and hopefully simple to someone here:
1) Can this type of lock be drilled like a traditional one, or is this style of lock specifically tamper-proof from that?
2) Does it even matter in this case... in other words, does anyone know if these things have batteries on the CPU board?
Seems they must have saved settings (time / date / menu options / etc) somehow... but I can't find one ANYWHERE that's visible. 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. 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. The lock would be easier to replace (but why bother if it doesn't help)...
