Agnus Removal
If you purchased the MegaChip board from DKB for an Amiga 2000/500
or are contemplating it, then you should be aware that removing the Fat
Agnus chip is no small undertaking. Even if you obtain the extraction tool
you will likely find it difficult to remove Agnus. I experienced bending
the tool up and finally having one leg break off without succeeding in
getting Agnus out. I finally had success by taking a small jeweler's
screwdriver and gently and carefully inserting it into all four corners of
the socket and prying ever so slightly a little bit at a time. Be very
careful not to pry to hard so that you don't damage either the socket or
the chip. By gently prying a little at a time and rotating around to each
corner you will eventually "break" the chip loose enough to reinsert the
extraction tool and finish the process of extracting the chip. You can
probably accomplish this by using one end of the extraction tool, but I
found it to be too "fat" to get the job done. A small, fine-bladed
jeweler's screwdriver was thin enough to get into the corners. You must be
quite careful not to pry to much. Just a little at a time in each corner
will eventually "break" the chip loose. It is in there pretty tight. I
know that this is not the "official" method, but the extraction tool the
dealers are selling with the board will not work if the chip is
well-seated. But it does work if you are patient and careful. It took me
the better part of an hour to work the chip out without causing damage to
either the chip or socket.
