The board has the form factor of a Cray-1 board but may have come from an outer part of an XMP. I have had a look in the module maps and can’t see a board type EH listed in either the Cray-1 or XMP + IOS + SSD listings. I don’t have maps for FEis or Disk/tape controllers. The air cooled fins on the side are very interesting and may have been either for external testing or fitment in a non-CPU type frame.

Thought to be a module tester extension board.

Very cool – the “see more cray” version. Actually worked on that exact machine’s unicos kernel. Thats Navier. In the good old days at NAS, everyone took a lot of pride installing those systems. When I was cleaning out my office last year, I found this coffee mug in my filing cabinet. May have come come from Cray (Chuck Breckenridge maybe) or the Pubs media team. Shows Navier October 1985 and on the other side, Stokes January 1988. A Y-MP soon to follow. I was working for the competition at that time – ETA Systems – where we could get comparable performance to the Cray 2 or 100ish MegaFlops – CPU to CPU – for well behaved codes (yeah – I’m trolling you all 🙂 )
