FS: 760mb Apollo Hard Drive w/10.4.1 -OR- Wanted:...

Maybe you weren't convinced, especially after the post from
Harry Selfridge < authoritative WD7000 word from HP. I began to doubt myself,
and went back and tried again.

I am speaking to you from a 11858-6 12191-5 with WD7000, 760-FA,
8 Mbytes of RAM, token ring, and 4-plane graphics, running
10.4, December 1992 (no patches).

Don't try this with 4 Mbytes of RAM: it takes 10 minutes to boot up.
As you can see, it gives a remarkably good impression of a
functioning node: not quite up there with a 32 Mbyte DN4500, but
nonetheless servicable.

As promised, here is the table for the 15652-1

Motherboard Boot WD7000
PROM supported

15652-01 12191-2 No (fails winchester disk self-test 1, just like 11858)
15652-01 12191-5 Yes (boots off 760-FA)
15652-01 12191-7 Yes (boots off 760-FA)

here's some more data on the subject:

my two (identical) DN3500s have a WD7000 with a 380-meg drive. here are
their motherboard and PROM revision:

motherboard: on the very left of the board, says 015652. on the top of the
board (left side though) it says Apollo Computer (C) 1987 Model 015653
[why not 015652?] Rev. 00; the boot prom is 12191 07. everything works
fine, no problems with the controllers or drives. one of the WD7000s has
an archive SCSI tape (internal) attached, works too.

I can take a hint :-).
More data. I've been playing with a few spare nodes (the alternative was to
help with Christmas
preparations: Scrooge is alive and well and working on Apollos) and have
following...

Motherboard Boot WD7000
PROM supported

11858-6 12191-2 No (fails winchester disk test 1 in self-test)
11858-6 12191-5 Yes (boots off a 760-FA)
11858-6 12191-7 Yes (boots off a 760-FA)

11858-10 12191-2 No (Fails just like a rev 6 motherboard)
11858-10 12191-5 Yes (boots off a 760-FA)
11858-10 12191-7 Yes (boots off a 760-FA)

15652-04 12191-2 No (fails winchester disk test 1 in self-test, just like
11858)
15652-04 12191-5 Yes (boots off 760-FA)
15652-04 12191-7 Yes (boots off 760-FA)

My experience with configuration #3 appears to contradict Tim's. This may be
because, when you fit the
system together for the first time, the self-tests take an outrageous time.
The first time I tried it, I
chalked it up as a failure, but noticed that the 11858-10/12191-5 - which I
expected to work - took a
very long time, so I went back to #3 and waited, and waited, and it worked.

The above combinations were tried with 380-FA and 760-FA disks, but only the
760-FA was bootable.
Neither of my spare 170 disks works at all, which was a bit of a surprise
(both crash invol option 7).

It looks as if, for the purposes of WD7000 support, motherboards of 11858 (rev
6 and up) and any 15652
will work with boot roms 12191-5 and up. 12191-2 just plain doesn't work.
Anywhere.

The 15653-00 mentioned above is the board revision as shown in copper on the
PCB itself. The barcode
labels say 15652-04. Sorry for the confusion.

I don't have a spare SCSI disk to try with the 11858-6/12191-5 combination,
but I think it should work.

Obvious questions:

What is the difference between 12191-5 and -7?
Why haven't I tried a 15652-1 motherboard?
Is it time to quit when you can remember the part numbers and serial numbers
of all your nodes?

I'll do the 15652-1 tomorrow

are as follows:

series 4000 rev 25 or later
series 3500/3550 Part #11858 rev 9, or part #15862 rev 1 or later

Don't give up hope yet. It could be that if you upgrade the boot EPROM
that
you will have better success. I have been trying to figure out exactly
what
combinations of DN3500/3550 motherboard and boot EPROM it takes to be
able to
successfully use a WD7000 and here's what I know so far:

config motherboard boot WD7000 760MB
rev PROM supported disk

#1 015652-4 12191-7 *WORKS* *WORKS*
#2 011858-6 12191-2 fails
#3 011858-6 12191-7 fails
#4 011858-4 12191-2 fails
#5 011858-4 12191-7 fails
---reported by Tom Brock, ---
#6 015652-1 12191-5 *WORKS* unknown, but 380 works
#7 015653-00 12191-7 unknown, but should work
#8 011858-6 12191-5 ?
#9 011858-10 12191-6 ?

It seems that the 015652 and above seem to support the WD7000. Once the
WD7000
is supported then both 380MB and 760MB drives should work, as well as
SCSI
drives with the right patches.

Some comments I have received indicate that a motherboard rev of 9 is
needed
for the WD7000, I can only assume that this refers to the 011858-9 as
the
0115642 and above support the WD7000 at a lower rev.

Please supply your motherboard part num/rev and boot prom rev and I'll
have
yet another piece of data.

I have reprogrammed the boot EPROM on config #2 and #4 above from rev 2
to rev 7
without any improvement. However, if your motherboard rev is not listed
above
as a failing one then you might have some luck by upgrading the boot
EPROM. I
have made HEX file images of the various boot EPROMS that I have that
can be
used in most popular EPROM programmers and I can upload them for access
if the
demand is high enough. You'll need a machine that can handle a AM29C512
or
AM29512.

I also have one DN4000 that was parted-out and so I salvaged the EPROM
from
that and turned it into a spare 12191-7. I may be persuaded to part
with it.

Perhaps we can gather yet more input and solve this puzzle completely?
If we can get Tom Brock to try 12191-7 boot EPROM in the 011858-10
motherboards along with the WD7000 that would flush out some more data.

Anyone else out there with working WD7000 configurations that would not
mind popping the cover and reporting motherboard and EPROM rev's????
