I talked to Adaptec sales just last week about this.  Apparently the B is
functionally identical to the A.  It sounds like they did some integration
(maybe an ASIC or two), and thus reduced the size from full-card to 3/4-card.

In other words, it sounds like it was merely a manufacturing cost reduction
project.  Of course, that's good for us because it probably means a power
consumption reduction.

I've never run their boards before, so I'm not aware of any warts or
problems which should have been addressed in a B.  I just ordered one,
and will be installing it with SCO ODT.  If anybody is interested in how
it works, drop me a line in about two weeks and I'll let you know.
