Hi!
I was unable to find the answers to these questions after a great deal
of online searching.
Can someone explain in detail what the differences are between the
XZ/Extreme Teal-colored Indigo2s and the Impact series Purple-colored
Indigo2s? (other than graphics benchmark info)
Is it only the graphics card set, or have there been changes made to the
motherboard, the overall system architecture and the power supply?
Is there a significant difference other than the case color, processor
speed and graphics sets?
Can the Impact series graphics sets be used in a 75 Mhz Power Indigo2
R8000, which was shipped with XZ?
Can the faster 150 mhz R8000 modules (often shipped in Onyxs &
Challenges) with the 4 Mb cache be used in the Power Indigo2?
Thanks in advance,
Vincent

Power supply, mid-plane, gfx.

Yup.

No difference. Even R10K exists in a XL/XZ/Xtreme flavour.

Yup.
No, no more difference (except the beefier power supply and IMPACT-ready
gfx midplane.

Nope. Only on R4K and R10K Indigo2.

No — besides, both of these are 75MHz R8000. R8000 came out in 75MHz
and 90MHz speed grades only.

Are you sure? Not that I have seen any R8k Impacts, but they have been
announced once. I think these are even mentioned somewhere on the
SGI website.

So are there 90MHz R8k Indigo2s?

Agreed. Never materialized, though, because by the time these could have
been ready, everyone seemed to opt for R10K Impact.

No.

um actually, MCE (www.mce.com) has some R8000/75 Solid Impact Boxes for sale.
There advertised on the web site so I’m assuming some where made?

oh, indeed they’re writing that.
— really interesting 
really really hard to believe (for me), maybe possible to build,
but i doubt, that SGI ever shipped one officially.
And assuming now that such a box existed, it’s definitely 100% unsupported !
With "unsupported" i mean you’ll never get any bugs fixed
which show up or are reproducible only on such a box.

No only never shipped it, but we literally never wrote the mgras (impact)
graphics driver for the r8k systems…
It would make an OK "Power Challenge M", but no much of a workstation
I’m guessing that they just meant that they put it in the purple case.
