Memory typeSixteen 30-pin 80 ns SIMM slots in banks of four, with 8 MB standard. Apple supported up to 64 MB using 4 MB SIMMs; its later support sheet lists a 256 MB technical maximum with larger modules that it does not support.4 MB soldered RAM and four 30-pin SIMM sockets; 80 ns or faster SIMMs installed in matching groups of four. Exact original UK brochure supports 20 MB using four 4 MB SIMMs or 68 MB using four 16 MB SIMMs. Current Apple support and the shared Service Source list the older 20 MB limit; their shorter supported-SIMM table does not describe the UK brochure's 16 MB modules. 1 MB ROM.
