it won't fit without some form of riser on the CPU socket.
I have a minimega chip in my rev5 a500 and the 1meg hack to give me 2meg chip ram, and i'm currently using a clockport adapter from individual computers in the 68k socket - to lift the vampire so it fits over the megachip board sat in the agnus socket.
it all works, but i can't fit the keyboard back in this configuration or consequently close the lid.
waiting for gold3 to move the chip ram into the vampires ram area and remove the need for the chipram on the amiga itself. then i'll be able to close the lid on my machine.
Many thanks, this are precious infos.
