#1Meg Agnus + 2.0
Joe,
To install the 1 meg Agnus in a 500, you need to cut 2 traces on the
motherboard and add one jumper. Not that hard, but you need a steady hand
with an x-acto knife and a soldering iron. You also need to have the right
kind of belly slot memory board. The generic 512k boards should be OK,
it's the larger ones that may be problematic. Some aren't designed
properly…
Upgrading the ROM should not require you to reformat the HD. The installer
program on the 2.x disk will update the system automagically.
I should have the 500 upgrade info around here somewhere… just have to
find it….
