My controller choices, too.  I don't know about the SyQuest, but I know
nothing goes faster than a DMA controller (except a better DMA controller)
and I want the speed.  1 MB/sec?  Congratulations, all!

I'll skip what Dave Haynie has answered, but mention a few things he didn't.

Someone here has a 2090 and a drive that doesn't spin up fast enough.
If it doesn't boot, C-A-A a second time gets it going fine.  Presumably,
the 2091 won't be any less friendly.  If you need it to boot unnattended
after a power failure or the like, more testing may be necessary.

>5) When will the A2091 actually be available?

I'm hearing reports they'll be available at World of Commodore next weekend
(near Dec. 1).  *Real* soon now.

If someone at C-A who knows could mention it when you start shipping the
things to dealers, I'm sure it would be widely appreciated.

>6) How many SCSI devices can the A2091 drive?

Like all SCSI devices (unless they have really $#!+ device driver software),
you can have up to 8 "things" on the bus, including the controller.
