I read the TWGS/ZipGS upgrade FAQ. I have a ZipGS 7/32 in one GS and a friend has a 8/16 in the other. One ZipGS (the 7/32) has two 32k chips in RAM area 1 and 2, but the 8/16 has two 8k chips in RAM area 1 and 2 (or is it 1 and 3?). How come I have 32k with 2 32k chips and he has 16k with 2 8k chips? If I want to upgrade by 7/32 to a 7/64, how many 32k x 8 25ns chips would I need? Thanks.
