spannernick i don´t think that is possible since amiga 600 only get´s maximum 2mb ram size what you are showing in the pictures is an accelerator card for the amiga 1200 not beeing compatible with a600 ,accellerator card for a600 is another story
oh i realized now are you trying to change the a600 and the cd for a1200 accellerator is that it?
well if it is the case is a very decent offer although i found kind of difficult since it is rather dificult to get a good price for an a1200 ac card
