Paul, There are two MAJOR obstacles to "Joe Average User" swapping out the Fat Agnus for the Super Agnus in an A2000. 1. The chip carrier (socket) is a square PLCC carrier. It requires a special tool to *properly* remove the chip. Attempting to pry the old chip out, or using an improper tool may not only get the chip out, but destroy the carrier. Replacing a broken carrier is an expensive proposition. 2. A trace on the mother board must be CUT. That in and of itself is no big deal, but the trace is very small, and quite close to other traces. If while cutting the trace, you slip…again you'll have an expensive repair to be done. On top of that, the Agnus, and many of hte other chips, are very sensitive to static. Improper handling of the motherboard, or Agnus can lead to a dead computer. For your information, the basic procedure is to open the computer up, remove the power supply/drive bridge, remove the old Agnus chip, move a jumper, cut the trace, install the power supply/drive bridge, put the cover back on and you're done.
