Charles Childers built retro Forth in a similar manner, generating code 
for a virtual Forth CPU, once you build a virtual machine for a 
particular CPU then the generated Forth Virtual Code will work on any of 
them. He has virtual machines for a variety of CPUs available. A virtual 
machine is simple compared to the development system so moving to a new 
CPU is much easier.
