I've just removed my old 8371 Agnus and replaced it with an 8372A Agnus.
Since I have a PAL B2000 with Rev 4 motherboard, I made the following changes:

	Move J101
	Cut  J500
	Cut  J102

Since making these changes, I've been experiencing "random" gurus. Only a 
few programs will run without guruing the machine. Trying to do more than
one thing at a time screws me up completely.

Kramden SI tells me I have:

Custom Chips:  Super Agnus, Normal Denise 
Memory List:                                           
     Address Range     Pri   Attr  Size  Description   
  $00200020-$003FFFFF   +0  $0005  2.0M  expansion ram  (I've 2Mb on a 2091)
  $000008E8-$000FE7FF  -10  $0003  1.0M  Chip Memory


Can anyone tell me if I have made the right changes for my machine?
Perhaps, I need to upgrade to a higher revision motherboard ?

ANY help greatly appreciated. It's awful not being able to use my Amiga
properly anymore......
