Depends on your definition of emulated.  Is an FPGA version merely an 
"emulation"?  You might say yes if it's a functional model.  Arguably no, if 
it's a gate level model.

Suppose you had schematics of, say, a KA-10.  You could turn those gates into 
VHDL or Verilog, and that should deliver an exact replica of the original 
machine, bug for bug compatible.  That assumes the timing quirks are 
manageable, which for most machines should be true.  (It isn't for a CDC 6600.)
