Gough) Newsgroups: comp.sys.mac.hardware Subject: MacII Memory Limit Message-ID: Date: 22 Nov 89 14:54:50 GMT Organization: Biology, Carnegie Mellon, Pittsburgh, PA Lines: 17 In the latest MacWeek there is a report concerning the use of 4Mb SIMMS in a MacII or IIx. Apparently 4 Mb SIMMs will not work in a MacII, without buying the FDHD upgrade, which includes new ROMs. There is also some difference between 4 Mb SIMMs made of 4 Mbit chips vs 1 Mbit chips, besides the obvious differences in size and density. Can someone clarify the situation. Is this a hardware design flaw, a ROM bug or what? When I bought my MacII it was supposedly capable of having 128 Mb of RAM, assuming 16 Mb SIMM's were available. Now I find out that the limit is 8 Mb, unless I spend more money on an upgrade. Sounds to me like Apple made a mistake, and once again the customer pays. Any comments?
