	Thats all you need to do.  I switched mine over 2 years ago
	with no ill effects.

	All current software (that I have anyways) works just fine. (The
	old pre-1.2 Calculator used to blow up on /0 errors).  Even A-Max
 	works properly with the 68010 (w/ 128K ROMS of course).  There is
	a PD program called "decigel" available in various places which
	patches the trap vector for the 1 instruction which is incompatible.
	I can't remember the last time I used "decigel".

> - What are the advantages of the 68010 ?

	About 7% speed improvement as measured by Jez San's Amiga Speed
	Program (recently on BIX and elsewhere).  This number is about
	exactly what I have experienced up to now, and I think it agrees
	with Motorola's own figures.  I think the speedup is noticeable,
	but then I can also see infrared and hear to 25KHz ;-), so...

Should you replace your 68000 with a 68010?  Well, they don't cost $60
anymore (what like $12 or so??), so you can't really lose.  You can always
go back...
