	Thanks to all who responded.  It turns out that the most crucial
difference is the fact the the Hardframe isn't readily available.  So, I
now own a A2090A and I'm very happy with it.  I think I would also have been
happy with the Hardframe.

	I had originally ordered the Hardframe since it cost $50 less --
a larger saving than what I had imagined.  Following up on my order a week
later I discovered that the Hardframes were on back-order whereas the A2090A
was in stock.

In summary, a brief comparison of Hardframe and A2090A:

*	The Hardframe can function as a hard card by mounting an
	appropriate hard disk to it.

*	The Hardframe doesn't require an Old-File-System partition to
	auto-boot as the A2090A does.  (The A2090A should be able to do the
	same in the future with new ROMs.)

*	Both are DMA (i.e., they're  f a s t  on large block transfers) and
	support up to seven SCSI devices.

*	The A2090A can also control up to two(?) ST506 (PC-type) drives.

Flip side,
