A couple of things that might help:
- assemble mboot.s and 'od' the result, so when you see something that matches
in the dump of the 0th block, you can look back at the assembler source, to see
what the source looks like
- read the boot block into a PDP-11 debugger ('db' or 'cdb' on V6, 'adb' on
V7; I _think_ 'adb' was available on V7, if not, there are some BSD's that
have it) and use that to disassmble the code
