always wanted an Amiga so got an A500 from ebay. It all works pretty much. One odd thing, I can't find a power switch on the unit anywhere!
If you aren't using the stock power supply, you might not have a power switch... It was on the power supply. ;-)
CTRL-Amiga-Amiga resets it, though, so you don't have to unplug/replug all the time.
