The older SunOS system runs very well on this, but condider that if you
need to use a "modern" hard drive, you will be limited to about 2GB (I think)
if you use one of the older OS's. That is why I went to NetBSD, it has kept
up with the latest hardware...
There may be firmware limitations on the location of the root
filesystem, depending on the SCSI commands used by the boot PROM.
I think you're correct that (in stock SunOS4) PARTITIONS cannot exceed
2GB, but I'm happily runing a 4GB disk (largest partition is 1.6G),
and I've seen 9GB disks on SunOS4 systems. You may not be able to do
absolute seeks to the 'c' partition with disk larger than 2G, but
that's never caused me any problems. I think there was also a
"disksuite" add-on, to handle large disks more gracefully, but it's
not needed.

I think that not being able to access greater than 2GB makes it difficult
to setup a large disk, even if you are keeping the individual partitions
to less than 2GB. I don't know the exact details, but the version of SunOS
that I had just wouldn't do it. Maybe there was a patch or update which
would have fixed the problem as you describe.
In my case, I wanted to use the IPX on a daily basis and be able to install
all of the latest applications (apache, qpopper, etc.). This is why I went
with NetBSD. I tried Linux, but it was dog slow on the sparc (see my previous
post about this).
If he doesn't have a real application for the box and doesn't require the
latest greatest software, then one of the old SunOS releases should be fine.

If you get 64mb of memory on the IPX even Solaris 7 runs OK (if you don't
expect too much of X-er-Open-Windows.
I'd assume at 96mb it would be pretty good.
I've only got 64mb on mine.

I know Solaris 2.6 runs pretty good on my Sparc 2 w/96MB, though
Netscape 4.7x is a little sluggish. Running Netscape was painful when it only
had 64MB.

Hi,
I need a little with my DG Eclipse. It was completely dead to start with
because
it had a fried front end power supply. The one that hinges out at the
back of the
machine not the one in the card cage. Luckily my machine came with an
expansion
card cage with had an exact duplicate power supply. I don't really need
the extra
50 or sixty serial ports in that expansion unit so I completely
disconnected it and
replaced the fried power supply board with the now spare one.
When I turned the power on things came to life. Slowly, the message
POWER UP TEST COMPLETE
is printed on the console but just as that happens, the machine shuts it
self down.
I have tried powering up with all cards unplugged with the same results.
It seems
to be the repaired power supply unit dropping out as I can hear it's relays
disengaging. I just don't know why.
Initially the power, battery and run LED's are on. Then the power and
run LED go off
while the battery LED starts flashing slowly. The BBU box is not
connected as I think
this machine was hooked up to an external UPS in it's previous life.
One good thing is that when I press the RST switch while the power is
still on, I get
an Scp-Cli/jp0 prompt and if I am quick I can run a command or two.
So my machine is basically alive but only for 30 seconds at a time. I
really want to get
it going because it has three drives with AOS and Business Basic on it
as well as a huge
9 track tape drive.
Any help would be greatly appreciated.
Thanks in advance,
Mike

Best place (apart from here) is probably comp.os.aos.
Doesn't carry a lot of traffic but there are still some DG and AOS types
hanging about in there.

New subject: PDP 8 peripherals
Hi all,
I have managed to get my PDP 8/M up and running but I don't have any
peripherals. So, here is my plea. Does anyone have or know of where I
might buy or trade for any or all of an RX02 floppy system, Tape drive
system or a hard drive for my 8M.
I am into restoration so my stuff will never appear on ebay.
Thanks,
Mike

Well, I have a 8E and 8L, and probably a 8F and 8M on the way, and yet
all I have for peripherals so far are RX02's... It takes a lot of
searching, unfortunately. And occasionally a lot of waiting.
By the way, to vaguely stay on topic, is there more than one type of
RK05 cartridge (aside from sectoring). I bought a few 16 sector RK05
packs, that have some sort of drive alignment programs on them, which
I'm assuming I can reuse as regular media. Will these work in all
types of RK05?

Yikes! If they are true DEC alignment packs, you should consider
finding people who will trade you regular packs for them. Please
do not use them for regular use if they are alignment packs!
As was mentioned in an earlier post, the PDP11 has 16 sectors and
the PDP8 has 12 sectors (did I get that right?). Since they are
hard sectored, they cannot be interchanged.
As I recall, the same pack is used in an RK05F, to get double density.
They achieved this by not letting you remove the pack, so they could
get away with twice the density (5MB), due to the pack not losing
track alignment upon removal/insertion.
There were many makers of RK05 like drives, all of which used the
same packs (as far as I know).
