[this is a cross-post from unix-pc.general where i got no response.  sorry
	if you had to read it twice. ]

In the recently-posted FAQ list, there was a statement (paraphrased here)
that you needed a 3B1 power supply and cover in order to upgrade from
a 10 or 20 meg disk to larger.  Then there was a vague statement that "there
are other ways around this" and something said about half-height drives with
faster access and more space.  Could someone elaborate on this (are there
60-70 Mb half-height drives out there with decent access times?)  Also,
does this also mean that there are other ways around having to have a
3B1 (instead of 7300) power supply?
