- Zeroth version of M68060 support (dont want to cause emulation traps for

Browse Source 
the "Fast Assembler Version of the copy loop)
- Yet another sanity check included: initialize unused receive buffers to
  zero sender id; and test for sender hardware id of zero in the receiver.
  Gives us better error messages in case flaky hardware causes spurious
  receive interupts.
