I have a Windows 98 computer which I bought 12 years ago. It still works, but the original CMOS backup battery is now dead.
The computer will boot normally, but I always have to reload the default settings before I can use it. It doesn't matter anymore, as I replaced the computer with a Windows XP system a couple years ago, but perhaps I'd better take that dead CMOS button cell out of my Win98 computer before it leaks (if -- gasp! -- it hasn't already) and damages or ruins the PC board on which it is mounted.
BTW: AiboPet, what is so special about your SNES game that the laser gun for duck hunt will not work with anything other than an analog CRT TV or monitor? I've never heard of that before. I would think that game would work regardless of what kind of monitor the console is used with, including modern flat screens.
