How do you test memory?

You can use MemBoardTest from Fred Fish Disk 158, though the length of some of
the A3000 memory addresses will write beyond the edge of some of the gadget
fields.  The Contents file says it includes source in Modula2, so if you have
a Modula2 compiler, you can probably fix it in short order.  But it's just a
cosmetic flaw and doesn't prevent the program from working on $7FFFFFC memory.

Can your dealer do it?

Yeah, by any of several methods, including:

 Chip Swap  = Some Bucks, but you get the suspect parts back if you ask for 'em
 Board Swap = More Bucks but you get new I/O chips (sort of like trading in a
	       6-month old Mercedes just to get clean ash trays).
 A3000 Swap = A good deal if you have a Commodore PET to throw in for trade :-)
 Fish 168
  or equiv  = You don't get to know what he found, so you might as well do it
	       yourself so that after this you'll know what's going on, unless
	       of course your A3000 is under warranty - then you go to the
	       dealer in any case.  Any CBM Authorized Amiga dealer should be
	       able to accomplish it, easily.
