Message-ID: <1991May24.121946.24471@magnus.acs.ohio-state.edu> Date: 24 May 91 12:19:46 GMT Sender: news@magnus.acs.ohio-state.edu Distribution: usa Organization: The Ohio State University Lines: 9 Originator: bgrubb@top.magnus.acs.ohio-state.edu Nntp-Posting-Host: top.magnus.acs.ohio-state.edu In the April 1991 issue of MacUser I read an article called "SIMMple Pleasures" by Owen W. Lenzmayer pg 194 that stated in a table on page 198 that you could INSTALL 16Mb SIMMs in the following Macs: LC, II, IIx, IIcx, IIsi, IIci, and the IIfx. This was fine except the same table said that of the 32bit clean Macs ONLY the IIfx could USE 128Mb(the LC maximum is 10Mb, the IIsi is 17Mb and the IIci maximum RAM is 32Mb). So my question is two fold: Will putting 32 bit clean ROMs in the II, IIx, and the IIcx really give you the ablity to USE 128Mb? and What is the problem with the IIsi and the IIci that they cannot use 65Mb and 128Mb respectivly?
