I am not sure, if you have already fixed this, but
the T_NMI case in trap() uses #if NISA > 0, but includes
a wrong isa.h (the one from .../isa, not the one from .../compile).
So isa_nmi() gets never called and cannot tell if the cause
was bad memory or check from bus..

Just added a button to nmi-line, printing a stacktrace on nmi
is _very_ nice, works on splhigh too :)

I found out that to acknowledge
an nmi one needs to set and clear bit 0x8 from 0x61,
otherwise it wont work again.
