Solved (!!!)...
The V11 is NO COMPATIBLE with all Impact boards.
Mines seem to be coming from R10K system (?).
The last V12 (good dump) improve compatibility.

Life is complicated!

I have used better eproms (10ns vs 12ns)...

Solid IMPACT was introduced slightly after High/Max IMPACT, so there's a possibility that v11 was made before Solid was a product. There's a big difference between Solid and High/Max with the absence of texturing, whereas with most SGI graphics the difference is in number of processors or amount of RAM (XS being the exception).
R4400 IMPACT systems were a factory shipped option. I've seen them reported as MG10 IMPACT or Solid IMPACT. R8k IMPACT was the unsupported config.
IP28 is sufficiently different from IP22 that I doubt you would get anything if you have a IP28 PROM plugged in.

If only all hardware (I'm assuming you mean EPROM burners) agreed on byte order .... except they don't.
I'm guessing your EPROM burner is connected to a little endian x86 PC, while the SGI is a big endian MIPS.

Personally, I prefer to store EPROM images in host-native byte order, so text strings are readable and e.g. IDA can handle them. But to each their own.

Yep, you are right ... But a lot of Hobbyists (normally constitued ^_^) use x86 machines for preservation/programation. (I think about MAME team...)
It's like you'd store a 16 bit program directly interleaved from two 8bits PROMs...

But, i had the chance to find your "not ready to burn" dump, so it's a good begining and i'll not complain ^_^;

A good stuff would be to update the nekowiki/PROM section. Just for saying that Solid Impact seem to be not 100% compatible with V11 Rev.

any programmer worth its salt should be able to switch byte and interleave order.

I have updated the Wiki earlier to reflect this compatibility issue.
