:(dillon@CORY.BERKELEY.EDU) quotes an article describing how to substitute
:a 68020 for a 68000 or 68010:
:
:> . . .
: 
:This encoding for ^LDS will fail in many strange and wonderful ways!  To
:appreciate the full potential for disaster, get a copy of the _MC68020
:
:> NOTE B:
:> 	^AS and ^RMC are OR'd together to create ^AS on the 68010 side
: 
:First of all, this won't work!  ^RMC is high except during Read-Modify-
:Write cycles, so the output of the OR gate would _never_ go low (the
:processor wouldn't get past the initial Reset vector load).

	I simply copied the signal description from EDN, June 20, 1985.
I double checked the items you cited and did not make a mistake.  Therefore,
assuming your arguments are correct, the article was in error.
