The NeXTcube is a versatile, easy-to-use workstation that can be utilized as a desktop monochrome system, true color 32-bit-per-pixel color/video workstation or file server system, all featuring NeXT’s object-oriented operating and development environment.

Whether used with the NeXTdimension board as a standalone workstation incorporating 32-bit-per-pixel color/video, or as a server on a network, the NeXTcube computer offers a tremendous amount of flexibility and performance in a single, one-foot-square magnesium cube. The system is built around the Motorola 25-megahertz 68040 CPU with integrated memory management and floating-point units, and includes the Motorola 56001 Digital Signal Processor for superior sound handling.

The NeXTcube may be equipped with 16 to 64 megabytes of main memory, and offers a variety of storage options – ranging from a 2.88-megabyte floppy disk drive to hard drives with capacities from 400 megabytes to 2.8 gigabytes. In addition, there are three available NeXTbus slots, so additional functionality can be added to the NeXTcube via NeXTbus expansion cards from third-party vendors or from NeXT, making the NeXTcube an extremely versatile workstation.

Product Details

 

68040 Processor

The 68040 is a fast and highly integrated microprocessor with a clock speed of 25 MHz. The 68040 contains 1.2 million transistors, more than any other microprocessor in its class. The incredible number of transistors is required because the 68040 is actually four chips in one – a central processing unit, a floating point unit, a paged memory management unit, and 8 kilobytes of cache memory.

The system clock speed is identical to the CPU bus speed, providing an average execution time per instruction of 1.3 clock cycles.

There are two 4-kilobyte memory caches, one for data, the other for instructions, along with burst mode read and write-back caching for improved data transfers.

56001 DSP

Built into the NeXTcube’s design is the 56001 DSP, a 25 MHz digital signal processor. With 24 K of static RAM cache, upgradable to 96 K, the DSP is dedicated to the task of handling digital signals – such as sound – at exceptional speeds.

The DSP is capable of generating compact-disc-quality sound: 44.1 kHz sampling rate with 16-bit resolution and full stereo.

Other uses for the DSP range from receiving still and video images to a variety of other data transmission and acquisition activities.

Network Support

Built-in networking, both thin and twisted-pair Ethernet ports are designed into all NeXT computers.

Network software and administrative tools are preloaded on all hard drives to simplify connecting to virtually any network, with no additional cards to purchase, install, or configure.

DMA Architecture

NeXT computers were designed to handle the most complex tasks efficiently. Rather than emulating a traditional PC or workstation architecture, NeXT systems used a direct memory access (DMA) architecture similar to that of mainframe computers for off-loading I/O functions from the CPU to the peripheral controller (PC) chip to maximize system throughput.

NeXTbus Expansion Slots

NeXTbus provides a multiplexed 32-bit address and data bus on a single Euro-DIN 96-pin connector.

NeXTbus architecture runs at 25 MHz and can support data transfer rates of up to 100 MB per second in burst mode.

NeXTbus is self-configuring: cards can be plugged into any slot and the system will automatically identify and configure each card.

RAM Configurations

NeXTcubes are currently available in 16, 32, or 64 MB RAM configurations.

RAM upgrades can be added incrementally in four-SIMM increments up to 64 MB of RAM.

Parity memory is also an option and can be ordered on a select number of configurations.

SCSI

SCSI is an expandable high-performance interface for connecting NeXTcubes to hard disks and other peripherals, such as the NeXT Color Printer, NeXT CD-ROM Drive, scanners, and other devices. Up to seven SCSI peripherals (including the internal hard disks) can be connected.

SCSI data transfer rates are up to 4.8 Mbytes per second (SCSI-I implementation).

A SCSI-II-type connector was used on NeXTcubes to provide high data reliability in CPU-to-peripheral connection.

Sound I/O

NeXT computers have been designed to accept and process sound.

Using the built-in microphone in the MegaPixel Display or an external microphone, voice messages can be easily added to electronic mail or used to annotate applications.

NEXTSTEP

Based on the industry’s first object-oriented system software, NEXTSTEP offers an elegant graphical user interface and one of the most productive development environments available today.

UNIX

NeXT’s operating system is based on the Mach UNIX kernel developed at Carnegie Mellon University, which features shared memory, fast interprocess communication, multitasking, and network support.

NeXT’s UNIX is compatible with UNIX 4.3 BSD (Berkeley Software Distribution).

Display PostScript

NeXT offers a unified imaging model, Display PostScript, for imaging on both the screen and printer.
