Your original question has already been solved, I guess, but regarding
nested interrupts - although I did not try it yet, IMHO reentrant interrupt
is possible, of course limited by stack and other resources. To preserve
status and W registers, you have to dedicate more memory and still there
will be short moments, when interrupts are disabled. Well, Sinclair is a
different beast... ;-)
