Eight DIMM sockets. Upgraded with one DIMM at a time.
Ships with a minimum of 16MB (two 8MB, or one 16MB DIMM) of RAM installed.
Requires 70ns, or faster, memory.
Can interleave memory for approximately 10-30% faster RAM access. For the fastest speed, sockets A1 & B1, A2 & B2...A4 & B4 should contain identical capacity DIMMs.
This computer comes with 4096K ROMs and a 1.44MB SuperDrive that uses high-density floppy disks and reads, writes, and formats Macintosh, Windows, MS-DOS, OS/2, and ProDOS disks.
Serial Ports with the phone icon and printer icon support synchronous modems, with handshaking on both output and input supported. Both Serial ports can be used with Apple's GeoPort telecom adaptor.
Sound output is 16-bit stereo output.
