Sorry I'm a newb. It's a a500 not sure what revision it is (can I find this out without opening her up?)
Thanks
No, but you can just open the trap door on the bottom, if it's got a card in it, gently remove it and check for a battery. If it's got one, and it's fuzzy, remove it. If it's got one and it's not fuzzy, you may want to remove it anyways. If there's no 501 expansion card, but your Miggy shows 1MB of ram, odds are you've got an A500+ board, so you may want to check it for a battery. Some had them, some didn't.
