I have a 712/60 in fine working condition, but the top case is darn near
splitting in half. If anyone happens to have a spare case in good shape,
I'd love to replace the cover on mine. Secondary to that, I also wouldn't
mind upgrading the memory to something bigger than the 32 MB that's in it
now. I'm in Indianapolis, IN.
Thanks!

James, AFAIK, the 712 uses common 486 (simm-72) memory, I just don't
know if EDO or FPM. I can test some in mine if you feel like. Mine is topped
with 192 (?) MB.

Interesting - I guess I just assumed it was a special config. I'm pretty
sure I have some 72-pins lying around here that I can try out. A quick
search says it needs ECC, so hopefully I have some of those...

72-pin SIMMs of all sizes (both FPM and EDO) seem to be going dirt cheap on Ebay these
days; apparently someone has found some value in the vintage computer maintenance market
and started manufacturing them. I can get 128 MB SIMMs of both types for $20 (128MB is as
large as a 72-pin SIMM can get, and not widely supported; I'm assuming the 9000 only
does up to 32 MB per SIMM, which is a common limit).

From what I've read, that looks correct. The
712/60, at least, has 4 slots
and is listed with a max of 128 MB. Guess I'll be
hitting the Bay and doing
my best to get compatible SIMMs.

The 712/60 and /80 have basically the same 4 slot motherboard with 128MB
max. The 712/100 motherboard has 6 slots for 192MB max. I have one or more
of each. A couple have the 16505A badge.

How many of yours have broken rear tabs or massive cracks in the cases? Or
is that just me...
9:16 p.m.
Mine has just the cover, no tabs, security lock, whatsoever :) It
already came this way, and doesn't affect me since I always use it closed,
with a monitor on top.

Most have at least one broken rear tab. Some are missing the floppy cutout
cover, or the cover is there but won't stay in place. No cracked tops
though.
I think these were designed for low cost and aren't as robust as other HP
systems of similar vintage.

For me it seems as sturdy as anything HP (older) I have. BUT it is made
of plastic, and plastic breaks...Old plastic breaks easier... :o)
I do love my 712 :D So bad mine isn't the 100MHz model, but I can live
with that :D
Now, If I could learn to use the inverse assembler... :oP

Auction 350478815109 should do the trick; if 10 is to many (but for $4 each, who really
cares?), there's 300621930749 ($5 each in pairs).
To the best of my knowledge, "parity" and "ECC" SIMMS should be the
same, since it's really just an extra 4 bits (and ECC is really a parity scheme when
you come down to it). The memory controller should be doing the heavy lifting, the SIMM
is just storage. Someone should definitely correct me if I'm wrong.
Also, to the best of my knowledge, the parity/ECC modules should work fine in standard
motherboards which will just ignore the extra 4 bits. I've not tried it, so I
certainly wouldn't vouch for it, but if you wind up with extra SIMMs, it might be a
worthy experiment.

Well shoot - tried every matched pair of 72-pin SIMMs I have and no dice.
Looks like the 712 takes FPM ECC. Must be none of my spare are that.

No. The HP9000/7xx SIMMs look, smell, taste like PeeCee RAM, but they
are different. You need the very special, propriatary HP9000 SIMMs for
that machine.
BTW: I know where half a dozend 712/64 with 128 MB or 256 MB RAM and
HCRX24 are sitting in a shelf. They will hit the dumpster some time
next year. We are trying to get rid of them for qite some time.
Maybe I'll try to sell them at the VCFe flea market... again...
