Holy. Man, you wouldn't believe the stuff I still get about A2090A's :)
For historical note, the A2090A Tech Notes was actually used as official
documentation for Commodore Canada's Amiga support service. When you called
up CBM Canada in Markham, and requested support for the A2090A, you'd get a
fax of the A2090A guide I wrote. That was a real honour.
It's funny how many Lego fans are ex-Amiga users...I sorely miss my A4000
WarpEngine040/28, GVP EGS/Spectrum, GVP ioExtender, and Hydra Ethernet. The
Warp's SCSI controller STILL outclocks my Adaptec 2940UW on raw data
transfer on UltraNarrow disks.

So you have the machine booting AmigaDOS but not LoadWB from the internal disk?

If you'd like, I have some spare Quantum LP52S' that would fit that A2091
just great.

Well, first off, I HIGHLY recommend you go with the A2091. For one, it's a
relatively "modern" (well, ca 1991 modern) implementation of a WD33C93 SCSI
controller, with true DMAC onboard, RAM expansion, plus implemented support
for all the good AmigaOS stuff like RigidDiskBlock, SCSIDirect (for CDRom
and tapestreamer access).
That said, you can set the BootPri of the A2091 to be lower than the A2090A.
Boot up in Workbench and launch HDToolbox from SYS:Tools (or was it
SYS:Utilities?) select scsi.device, and set the BootPri lower than the
A2090A's disks.
You can also probably configure the A2090A's BootPris lower, but it requires
using the Prep software on the A2090A Install Disk. Ick, and it might
rewrite your bootblocks.
BUT, that all said, it's really much easier to work with an A2091. Just
make sure you have a DMAC04, and at least REV 6.6 ROMs, and you're flyin.
Let me know if you need smore stuff for your Amiga.

I got a Sopwith Camel and really rather enjoyed it. It's quite a pretty
model and I like it a lot more than I expected.

| (...) That's cool man. I think I was one of the last people to get a 2090A and not be eligible for the upgrade deal for a 2091. The entire time I had this Amiga I wanted to upgrade to a 2091 but could never get the money together to do it. I finally (...) (22 years ago, 21-Jun-02, to lugnet.org.ca.rtltoronto)
