A fine bit of hardware.

It looks interesting.

Its a dog slow hardware. For standard tasks the R10k Indigo2 is the better choice because its "usable" for a hobbiest :).

The last time i upgraded my old Power Indigo2 to .22 i keep notice that the prereq tools are br0ken. So be sure that you have working .17/.18 around.


Nothing appears to have been posted since.

Activity now -- all it took was questions. :-)

Anyway -- my question:

The internal SCSI connector to the sleds is the same physical
connector as the newer SCA drives, but (from probing from one of a pair
of sleds which I got via eBay), the power pins at least don't seem to
match the SCA pinout. Did I probe incorrectly, or is this truly the
case?

Use an adapter. These are not standard SCA.

O.K. That agrees with my probing of the +12V and ground pins
from the drive power connector. I've got at least one adaptor to use,
maybe two.

What is the latest version of Irix which will install on a
Indigo 2 with the R8000 CPU? I do understand that it is an unusual, and
relatively rare CPU, so I don't really expect the latest Irix to still
support it.
Irix 6.5.22. Note, though, that Irix 6.5.22 comes as a set of four overlay
CDs. These are for upgrading from an ealier full release of Irix. You
will also need the set of CDs from the base installation. Mine are from
Irix 6.5.8. You need:

Irix 6.5 Foundation 1
Irix 6.5 Foundation 2
Irix 6.5 Applications

O.K. A lot of shuffling of CDs then.

Copy all disks to your Install Server (Linux/*BSD/IRIX) and do a network installation other way do like a DJ!
