OK ! The explanation is very clear now ! So the pass-through port on the A1010 can only be used for self-powered floppy drive (not the A1011 for example).
This is incorrect!!
There's no such thing as a "self-powered" A1011 or A1010. :lol:
When I had my A1200 and two drives, I had an A500 power supply hooked to it. When I had my last A500 and used 2 external drives, I had a PeeCee power supply.
Currently, my A1000 with its regular power supply powers 2 external drives, an ICD AdSpeed chip AND an external 2MB RAM board.
You're supposed to be allowed to hook up to three external drives to an Amiga computer. All the big box Miggy's can handle 'em anyway. You guys with wedged-desktop computers need heavier duty power supplies is all.
