Remarks:
The Macintosh Plus is the fourth model in the Macintosh line. It uses a MC68000 CPU running at 7.8336 MHz. It has 32bit internal registers and a 24bit address bus. No coprocessor is supported on this model. It has 128k of ROM and supports memory sizes of 1,2,2.5 and 4meg. The Mac Plus also has no hardware memory management and no slot expansion. The sound comes from a RAM based mono sound buffer. The Plus is the first Mac to have an 800k floppy drive and can support a 400k or 800k external floppy drive. A SCSI port made its debut on this model and two mini-DIN serial ports are available. The 9inch display provides a black and white image at 512x342 pixels. The Mac Plus keyboard also came with a numeric keypad unlike earlier models and the mouse connects on the back via a DB9 connection. This Mac plus has 4 meg installed from the factory and is complete with mouse and keyboard. This is a later plus model that has a platinum colour rather than tan like the earlier mac models and the Apple ][ series. This machine is in great shape except for some glue remaining from a glare screen that was previously installed. It also has the programmer's switch on the side that says INTERRUPT and RESET. These allow users to stop the computer and invoke additional commands or perform a reset without powering off.
