 From their comments, I suspect it is a genuine 68000.  I'd even wager
an aircraft carrier without even seeing it!  Almost definitely *not*
an '010 (as the '010 added very little of value to a typical embedded
system).  OTOH, there were few contemporaries that had the processing
power of the 68k in that market.
