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.
