To be more specific, initially I want to replace the Java VM in JOP with a Racket VM. JOP is great as a starting point because it has many useful things available from the start: support for USB and serial interfaces to load the bytecode from the PC, memory interfaces, floating point unit.
I haven't looked into the Scheme-79 paper yet (thanks for the reference by the way!).
