While talking about the emulator approach... just recently
I stumbled across an Open Source emulator called QEMU... which
seems to cover several CPU types, not just PA-RISC... yet...

Makes me wonder if this could be an interesting starting point
for trying to get a PA-RISC hardware emulation implemented...
