Well here's an odd one, check this out:



Those familiar with Indy CPUs will immediately figure it's an SC R5K model, but note the 'R5-150PC' sticker and the oddly placed PN sticker aswell. it certainly has all the extra ICs & cache normally present on an SC version, but it shows up and behaves as a PC type, ie. no L2 at all. And the PN sticker does look like it's covering up a normal SC type PN.

This is the first time I think I've come across a CPU which has been used by SGI in this way, though whether or not it was a faulty part repurposed as a PC model (standard practice with x86 & GPUs, ie. binning) or instead is an SC they deliberately modified in order to satisfy a PC order (like the AV board socket cover for O2), who can say.

Anyone else encountered SGI parts which are marked and operate as something other than how they appear?
