I have this night (after four days of searching) found a bug that
caused machines with physical memory not an multiple of 16K to
hang. This was the main problem with MVII/III hanging, because
those machines uses a few hundred bytes at the end of memory for
some internal use.

I have also written code that actually halt or reboot an MicroVAX
regardless of the switch at the backplane.

Now I'll jump down further into the code to find more bugs :-)
