Flobynoid 9.8 crashes on boot...

When I look at the trace, I see this prior to the loader crash:

Obviously BBS5 is not a valid opcode in this case -- so why would flobynoid jump to this address when there's no program code there?  I see it activate 80 col and 80 store prior to this -- I didn't munge the softswitch implementation for aux reads did I?
