Another thing that surfaced recently on my pile is a manila envelope containing
a big photocopied stack of papers, with a title page saying:

It’s got about 45 pages of text, interspersed
Al,
I have the original Motorola paper version of AN1123. I’m happily to scan
it for you.
I have a pretty complete set from an139 into the 1100s if there are others
you need.

So in the continuing quest of fixing my second RL02 I replaced the heads
and found the drive was slow and would generate about 80 block errors on
a pack where my reference RL02 drive would never generate more than 10.

That's reportedly what DEC thought of it, but in practice it was SCSI done
differently so as to be incompatible. The only

Greg,
Thanks for the response. The article you reference is also the one bit of
documentation I was able to find. It's been a big help. I have been in contact
with Bob and recently picked up one of his RAM/EPROM boards to use while I get
the system restored.

Hello all,
I used Amigas for several decades and I really liked SCSI. The
problems with the Amiga and SCSI were related to firmware and not the
hardware. It was important to use the latest SCSI Roms on the 2091 and
the 590. The A3000 did have a problem with the hardware. If you upgraded

Given the reference to the Amiga, almost certainly SCSI-1, i.e. 8 bit

I am interested in Gene's comments about the design of SCSI, but I
don't know enough electronics to judge.
I thought others here might.
I have trimmed the mail a little to the relevant parts.
