Right. I've not looked at this. It never worked for me and I think its to
do with the "new" event mechanism bssed around the interruptPending inst
var. So for now I use an image that has a read-eval-print-loop in it.
Much better would be for the input scheme to work. But I've not had time
or occasion to look at the Interpreter and update StackInterpreterSimulator
appropriately so it responds to input.
