The "raw" board is the same. 128Ks have 4164 chips. 512Ks have 41256 chips. There is a place on the lower right of the board for the required additional multiplexer chip which is for the two additional address lines. This is not "stuffed" on the 128 and is on the 512. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are a member of the Vintage Macs group.
