However....on a modern z9 you can probably run Hercules and get as much speed as you ever would have on a real 370. Hercules can emulate a 370 very accurately, and if you can license the system to your actual CPU, then it might even be legal. I doubt anything specifies WHAT the intervening virtual machine layers are. Adam
