The A1000 comes pretty close.  The 86 pin edge is specified as being capable
of supplying 1 Amp at 5 VDC.  That's about enough for a Zorro interface and
maybe a 2 meg memory card (done right), certainly not enough to power an
8 meg memory card or a hard disk drive (though it could power a hard disk
controller if you used a self-powered drive).  The A500 shouldn't have
anything unpowered extra added to it other than a second floppy and the
internal RAM card.  NO EXCEPTIONS, you really don't want to fry your A500
power supply.  Or perhaps worse, lower the resulting system voltage 
to the point that the machine runs, but runs flakey.
