| Blue Ram 32K Add-On Schematic One page schematic designed by Ken Lill in October 2006. This is a highly readable PDF that Ken uploaded to the Bally Alley Discussion Group on January 24, 2007. A few notes directly from Ken: "This is all on one page, except the different configurations for different SRAM chips. The page already posted shows memory configurations, but it doesn't show hoe the ~CE connection is connected when multiole chips are commected (E.I.) 8K x8, 16K x 1, etc." Thanks Ken! |
