I always wondered why a carry or borrow from the stack pointer couldn't
have at least generated a branch to some known location.  It may not have
exactly told you where your code went bonkers, but it'd be better than
letting the program run wild!  How many micros used a local stack?  The
Natoinal PACE is the only other one that comes to mind, but at least it had
a "stack about to overflow" interrupt and a way to access the stack
directly.

Were you a Datapoint employee?
