part number for Sparc64 X+ is MBCS450515B
so this is can be a Sparc64 X due the part number very close, also layout is the same
ES not mean for Engineering Sample |

Great! Thanks isa-d
Is this "ES" more of a sequence number or a plant code?

Don't know, I have 4/5 Fujitsu Sparc and SparcLite CPUs either in ceramic and plastic with ES marking
I don't believe to be so lucky to find so many engineering sample  |
