Uh, okay. Micropolis being out of buisiness really makes things
tough for owners of these drives.

Well, for one thing, Ultrastor is out of business, also. It doesn't
look like they made too many of these 24MHz controllers (most of the
ones I see offered for sale will not do 24MHz), and to make matters
worse, individuals who *do* have them either won't sell, or want
and arm and a leg for them.

Well, I know of only two other *solid* possibilities: The OMTI/SMS
8640, and the DTC 6282-24. ANother one is iffy: the WD 1009.
I have gotten mixed reports on this one: SOme sources say it will
do 24MHz no problemo. Some say no way Jose. I've been looking for
all of these. Zip. Nada. (Unless I was willing to fork over $90
to a dealer for an 8640.

Uh, I know what you've got in mind, but you will not be able to
swap the "interface" board to a different HDA. Reason is, when
these are made, the board is 'married' to that HDA using jumper
settings and stuff (the ones with glyptol dripped on them so
you can't remove them by accident). Each one is different (it has
something to do with the servo head, I think).
