I'd say you were very lucky, I assume the controller was
already in the machine. I've successfully pulled a card from
a slot, but plugging them in, well, you can do it, but it tends
to crash the software. I've heard so many "was off one pin
and blew up my Disk II drive or controller" that I now only
plug them in with the card in hand and facing me. ;-)

I've never blown a daisy-chain controller either, but I know
if you hot-plug a 3.5" drive, they won't operate. Something
on the drives controller tells the onboard controller that it's
there when you boot up. Even a warm boot won't do it.

Ah-ha! Another old head like myself. However, all my 80's 8-bit
experience is on Atari. Making the transition to the Apple II line
is to say the least, an adventure to behold. ;-)
