You can still buy these two platforms; the hardware, if memory serves, contains Intel Xeons with special microcode.

At least for the Dorado (the line that began with the Univac 1107), I think it's more like "with an LLVM-based binary-to-binary translator":

They may have done the same for the Libra (the line that began with the Burroughs 6500), although it would need to handle the tag bits (they probably stuff the 48+3-tag-bit words in 64 bits).
