Macintosh Plus, SE, Classic: 1MB SIMMs Only


I know that System 7 allows a Macintosh II-class system or a Macintosh
SE/30 to access more than 8MB of physical DRAM, and the use of
higher-density SIMMs. Is the same true for the Macintosh Plus and
Macintosh SE? Can I now put in four 4MB SIMMs and have 16MB of RAM in my
Macintosh Plus, Macintosh SE, or Macintosh Classic?

Neither the microprocessor nor the system software determines the type of SIMMs
the system can use. This depends on the electrical design and the
Memory Manager. The Macintosh Plus, Macintosh Classic, and Macintosh SE
have address lines that support only 1MB SIMMs.
