[LMH]Checking in as well....

[Daniel Seagraves]

Loaded the E1 boot PROM (You guys were right, it's written backwards!
I guess the address lines were active-low...)

Up to microPC 8.  The one at 4 confused me for a little bit
because it causes an infinite loop if there IS a pagefault (since
the uPCS is empty it goes to address 0)

The instructions at 2 and 5 might be incorrect; They don't do anything
except ABV-Jump to BUSERR on a bus error.  (It does BYTE operation 0,
which just turns on the LSB  of the M-bus, and doesn't do anything with
the output.  I think that's just the microcode looking for a bus-error
and trapping it.

Here's a snapshot:
