I'm not sure which //c's you're talking about, but there was a routine
published in _A+_ that boots the external drive on Apple //c's.  I
have the UniDisk //c, and it works on mine, as long as you use ProDOS.
This routine should be on my webpage in a week or so.  (It's there
now, but I archived it incorrectly, so it's corrupt.)
