Mac iifx memory subsystem
Posted by: moving2 on 2023-09-08 15:34:37 I've read different things about the iifx's special memory subsystem (separate r/w lines on the 64 pin simms, latched writes, etc) in Macworld and other pubs, but I have yet to find a detailed technical description of how it works. Can someone point me to a publication or any reference with this information?
Posted by: ClassicGuyPhilly on 2023-09-08 15:57:10 While I can't help with the technical documentation, here's the May 1990 Macworld with the IIfx article (page 280). It's a great read for any IIfx aficionado.. https://vintageapple.org/macworld/pdf/MacWorld_9005_May_1990.pdf
