@SamuraiCrow:
Never use screwdrivers to extract PLCC-chips, especially not with old sockets as the plastic gets much more fragile with time. With an old A500, it will most likely break.
Most electronic stores sells
these, which are very cheap and will make the extraction very simple without breaking any PLCC-sockets.
If anyone is wondering, this is only for the Agnus chip, which is a PLCC-chip. All other chips are regular DIL/DIP chips.
