Macintosh IIsi Features and Benefits
The Macintosh IIsi is the lowest-cost member of the Macintosh II line. It is
equipped with a 20-megahertz 68030 microprocessor that runs Macintosh
applications up to five times faster than the Macintosh Classic. This allows
you to work under A/UX.
The Macintosh IIsi comes with built-in support for four Apple monitors as
well as third-party monitors. A video expansion card can be added if you
need to use any other Apple or third-party monitors.
An internal expansion slot for either a NuBus card or an 030 Direct Slot card
allows you to add one of the expansion cards that are available for
communications, video, or coprocessing. An optional floating-point math
coprocessor can be added to speed mathematical calculations. Eight external
ports allow you to connect peripheral equipment.
Sound input is available with the Macintosh IIsi. The unit comes with a
microphone and phono jack adapter, which let you input your voice into
documents, presentations, and even electronic mail messages.
The Macintosh IIsi will run applications supported by system software version
7.0.

Macintosh IIsi Technical Specifications:
The 68030 microprocessor runs at 20 megahertz and features a built-in Memory
Management Unit (MMU). The MMU supports the A/UX operating system and
provides the capabilities necessary to support virtual memory, a new feature
of Macintosh system software version 7.0. Virtual memory lets you work with
more applications without the need for large amounts of DRAM by setting up
sections on the hard disk for easy memory swapping. There are 256-byte data
and instruction caches that accelerate overall system performance by
eliminating one wait state that occurs with the 68020 processor.
Customers who work routinely with software such as sophisticated CAD/CAM and
graphics applications may want to add the Motorola 68882 floating-point math
coprocessor to their systems. The 68882 optimizes the computer's performance
during math-intensive calculations.
The Macintosh IIsi comes with 1 megabyte of RAM on the main logic board. Up
to 16 megabytes of RAM can be added by installing Single In-line Memory
Modules (SIMMs). Some possible configurations include:
-- 2 megabytes (1 megabyte on main logic board; four 256K SIMMs)
-- 3 megabytes (1 megabyte on main logic board; four 512K SIMMs)
-- 5 megabytes (1 megabyte on main logic board; four 1-megabyte SIMMs)
-- 9 megabytes (1 megabyte on main logic board; four 2-megabyte SIMMs)
-- 17 megabytes (1 megabyte on main logic board; four 4-megabyte SIMMs)
The Macintosh IIsi uses 100-nanosecond (or faster) fast-paged mode RAM.
A ROM SIMM socket on the logic board provides an easy ROM upgrade path.
One NuBus card or 030 Direct Slot card can be added to the Macintosh IIsi by
connecting it to a Macintosh IIsi adapter card (sold separately). NuBus
provides a multiplexed, 32-bit address bus and data bus on a single 96-pin
connector. The NuBus architecture supports data transfer rates up to 3.75
megabytes per second. The 030 Direct Slot provides a 32-bit slot directly to
the microprocessor via a 120-pin connector. This slot is compatible with
expansion cards available for the Macintosh SE/30 personal computer. The
Motorola 68882 floating-point math coprocessor is on the adapter cards.
The SCSI (Small Computer System Interface) is an interface bus used to
connect hard disks and other SCSI-based devices, such as the AppleCD SC
CD-ROM drive, and Apple Scanner, and the Apple Personal LaserWriter to the
Macintosh IIsi. This interface can support up to seven SCSI peripheral
devices.
The Macintosh IIsi provides full ROM support for all AppleTalk protocols, and
includes built-in serial ports for LocalTalk 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 Home, Addresses with Audio, Appointments with Audio, Audio
Palette, and Audio Help stacks are included. A/UX version 2.0.1 (optional)
is compatible with the Macintosh IIsi.
The Macintosh IIsi has been designed to accept and process sound as well as
generate it. Using a microphone or phono jack adapter, and appropriate
software, you can speak into the computer to create electronic voice messages
and add voice comments to files. Sound entering the computer is monaural,
8-bit sound. It is filtered through a custom filter/preamplifier chip,
converted to digital form, and stored in DRAM or directly on the hard disk.
An Apple electret microphone and phono jack adapter are included.
