I turned BEVENT off and it boots successfully. I am
not immediately
sure why this is necessary.
If an LTC interrupt happens before the OS has set up the LTC vector, etc,
hilarity ensues.
E.g. the LTC has to be turned off before UNIX V6 will boot on an -11/23:

I discovered this the hard way; I roached the disk on my simulated /23
when I didn't.

That's weird. Isn't the interrupt disabled by RESET?
