Hold on a sec: Shift-Reset does not go thru the keyboard encoder chip.
If it doesn't work, there is some *other* problem.

Multiple H: prompts say that either the CPU board is getting multiple
RESET commands from the TLB, or that the CPU board itself has some
problem that is causing it to randomly reset itself without any command
from the TLB.
