Physical DescriptionThe Macintosh 128 computer is a beige coloured plastic desktop unit containing a 9" monochrome monitor, a single 8 x 10" motherboard, the power supply and a 3.5" disk drive mechanism. The four-layer motherboard, in the bottom of the case, includes an 8mHz 68000 processor, 128K RAM, 64K ROM, clock/calendar chip and several proprietary VLSI chips. At the rear of the unit are interface connectors for the mouse, a printer port [RS232 connector], modem [RS422], sound output and external disk drive. The interface connection for the keyboard is at the front. There is a small clip on hatch that reveals a space for a 4.5 volt direct current cell at the rear. The system cannot be expanded internally except for the RAM being replaced by 256K chips, providing 512K RAM. The power supply is mounted vertically on the left side of the case and the system has been designed to operate without a cooling fan. The screen displays a 512 x 342-bit mapped screen, using square pixels, that is almost identical to the Lisa screen. The disk drive is a variable-speed, single-sided, 3.5" Sony drive offering 420K of formatted storage. Three more drives can be daisy-chained from the drive extension connector.
