This may not be old enough for the OP, but...
Around 1987 or so we were setting up a SCO box on an ALR 386 machine. There was a software product that allowed for striped arrays of SCSI disks with a parity drive in that environment. I want to say it was called something like Paladin, but I can find no reference on it.
Didn't work with the Fujitsu drives we had. Kept hosing the superblock due to cache writeback issues.

Hello,
I got your email off of your website and I was hoping that you could help me
The company I work for here in the great northern state of Maine decided to clean out the server room one day and was going to throw away a great piece of computing history
so I rescued and took it home
I had done some research and I know there is some demand for this type of computer among collectors
. is there a website to find out possible market value and maybe a buyer? This is what I had acquired:
Hewlett Packard- HP-87
HP82909A-128k Memory Module
HP82929A-Programmable ROM Module
HP82936A-ROM Drawer w/ six (6) ?ROM chips?(?)
1. Plotter ROM-Rev. A
2. I/O ROM- Rev. A
3. Advanced Programming ROM 1- Rev. B
4. Advanced Programming ROM 2- Rev. B
5. Electronic Disc ROM- Rev. A
6. Assembler ROM- Rev. A
HP82939A-Serial Interface
HP9121-Dual 3-1/4? Floppy Drive
HP82905B-Printer (Dot Matrix, I believe)
Ten (10) Floppy Disks, (to be named later if needed)
Pocket Guide Instructions...
File folder w/ original invoice for parts of the system and misc. paperwork..
The HP-87 works well, I plugged it in and was able to type commands, nothing too complicated
.i didn?t test the floppy drive or the printer yet
I need another power cord
which I can dig up
system is clean, though slightly (very slightly) discolored from age
Please let me know if you have any resources for me to follow up on
I have considered posting it on Ebay, but I would like to get more info on it before i do anything
in the meantime, I will check it out and see what it can do!
Thanks for your time and effort,

Hi,
Posted a few days ago looking for early, circa 1987 implementations of
RAID beyond RAID0 and RAID1.
In my research, I've come across a fellow named Jan Janku, who proposed
some advanced ideas in 1986.
Does anyone know of him or where I might contact him?
TIA for any response,
steve

www.openpa.net is your friend.
Don't have anything that new; a C180 will run standard kbd/mouse and perepherals just fine.
What graphics do you have? HP jumped on the next big thing, the EVC connector, really fast.
I don't think anybody else did. Finding an adaptor can be fun-. The newer FX5/FX10s I believe have
DVI, though.
The apps disk does appear to contain cc and cxx. Don't know if they have fixed license policies in place or if you just
are asked nicely to get a license from HP. To do that, you either (a) get a commercial software product for HP-UX developed or
(b) you send them a check for about $900. HP-UX does have all headers, so GCC is an option if you have cycles to burn
(don't even think of using anything less than GCC 3.3 - it seems to, um, "pessimize" programs on RISC architectures)
I'll play around with the C180 and check out the apps- I have more disk space there (wohoo! 6GB!)
Sorry, forgot a few things.

Forgot to add:
Scuzz hasn't had any problems with my original HD on
his A600.
and here's the reason I thought it might be a
resistor:
" The different PSU would not cause
overheating inside the A600. Since the PSU is
located separately, the heat it dissipates
would be outside of the machine. Even though
the PSU is capable of supplying more power, it
will only output the power that is needed.
I would take off the top lid of the computer
and try to pinpoint where exactly the heat is
coming from. There could be some components
that might have shorted out and is causing
the power supply to output more current. This
could actually be your original problem. The
old A600 PSU probably wasn't able to handle
this current draw but the more powerful A500
PSU could. If something shorted out (like a
resistor) it would cause other components to
heat up and that might be what your seeing.
Amiga install any fuses in the computer I have
no clue. Wouldn't have cost that much extra."

Ok, here's the full story :
I have had my Amiga 600 since 2001 and have
added a few bits over the years:
- 2.5" 4GB harddrive (I can't remember the
make and model at the moment)
- 1MB RAM (in trapdoor underneath)
I also have a 4MB PCMCIA RAM card which is
rarely used, and 2 external floppy drives
(one doesn't work), with only 1 connected up.
I haven't upgraded any of the kickstart or
ROM chips, they are the same as when I bought it.
I run WB2.05 (and am happy with it) with
kickstart 37.300
I don't know the board revision number off-hand
but I can find out if required.
My harddrive used to power down (powersave?)
after not being used for say 20/30 mins and
happily power-up again whenever I tried to
access the drive (via WB or via AMOS BASIC).
However, around April/May this year the drive
started to randomly power down and then,
usually, almost instantly power back up again
but WB nor AMOS could access the HD. Any
attempt to do so would freeze WB or AMOS.
I figured (as you would) that my harddrive
was playing up, so I copied all the important
files to 26 floppy disks (fun!) - 880K each,
you see.
A mate (Scuzz, who owns the
http://www.commodore-amiga-retro.com website
and the equivalent yahoo group), and die-hard
retro (especially Amiga) enthusiast offered
to use my HD as a slave and copy the files,
as best he could, to his PC and burn them
to a CD for me.
In the meantime I got myself another HD,
which happened to be the same make as my
last one, with WB3 on it (it has a Locale folder,
files I didn't see on WB2 and a 68040.Lib file).
This new HD has exactly the same problem :(
I popped along to www.amiga.org and posted
my problem up there and peeps then suggested
it might be a flaky PSU. I got myself an
A500 "heavy brick" model (AFAIK it's compatible
and gives more power if required) by chance
(I was planning to get another A600 PSU)
>from www.amigadeals.co.uk
Everything appeared to be fixed. However, my
A600 was running hotter than normal. I have
always put a plastic pen above the air vent
bit at the top of the machine (by the F1-F4 keys) an
d it used to always be cold. With this
new PSU it was warm and the underside of the
Amiga 600 was hotter than normal.
I posted my concerns to either Amiga.org or
CAR and then someone suggested that it might
be a faulty resistor. He claimed that the
A600 PSU didn't have enough power to supply
the machine with a faulty resistor (thus
causing the HD to shutdown temporaily) and
that the A500 PSU did, and the extra draw from
the board (caused by the faulty resistor)
could be sustained by the A500 PSU, thus
causing the extra heat.
(I could look up what he said and quote it
tomorrow, if it helps?)
Phew!
I hope that all makes sense.

Cool :) Were you ever tempted with the Model

Did anyone other than Motorola use VERSAbus in their products? I get the
impression that a few companies bought into the standard, but I'm not sure if
it had morphed into VME before anyone seriously used it.
(I picked up a Motorola 68000 SBC earlier that has a VERSAbus interface on it,
hence the interest)

Q. What's wrong with top posting ?
Hey guys,
OK... I went to the site and completed the application. At one point during the "signup" process, the server choked and could not complete the process. I never did recieve a "comfirmation" screen or a DOWNLOAD / CD option . I did however receive an email with a "software delivery receipt" including the download key.
When I went to the URL, I was given an option to download the app. I'm using dialup so downloading is not an option. Do I have to complete a different request or will the CD's automatically be sent?
Thanks, SteveRob
