- Macintosh Classic Technical Specifications
-
- Copyright 1990, Apple Computer, Inc.
-
- Two configurations of the Macintosh Classic are available. The Macintosh
- Classic comes with 1 megabyte of RAM, internal 1.4-megabyte Apple SuperDrive
- floppy disk drive, ADB keyboard and mouse, system software, and training disk.
- The Macintosh Classic 2/40 comes with 2 megabytes of RAM, internal 40-megabyte
- hard disk drive, internal 1.4-megabyte hard disk drive, internal 1.4-megabyte
- Apple SuperDrive floppy disk drive, ADB keyboard and mouse, system software,
- and training disk.
-
- The Macintosh with 1 megabyte of RAM can be expanded to 2 megabytes by adding
- the Macintosh Classic Memory Expansion Card. The 2-megabyte Macintosh Classic
- can be expanded to 4 megabytes by installing Single In-line Memory Modules
- (SIMMs).
-
- The SCSI (Small Computer System Interface) port is a bus that used to connect
- hard disks and other SCSI-based devices to the Macintosh Classic. It can
- support up to seven SCSI peripheral devices (six if you have an internal hard
- disk).
-
- The Macintosh Classic provides full ROM support for all AppleTalk protocols and
- includes built-in serial ports for Local-Talk network connections.
-
- Macintosh system software includes:
- -- System software version 6.0.6 or later (the Macintosh Operating System)
- with System Startup disk.
-
- -- System Additions disk (includes utilities such as the Apple File Exchange,
- HD SC Setup, CloseView, Disk First Aid, and Font/DA Mover).
-
- HyperCard 2.0 software is included with the Macintosh Classic.
