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.
The NeXTcube was introduced in 1990 and discontinued in 1993.
Overview
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. This 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.
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.
General Information
CPU
The NeXTcube is powered by a Motorola 68040 processor clocked at 25MHz, with an integrated FPU. The system also features a 25 MHz Motorola DSP56001.
- 18.6 Dhrystone MIPS
- 2.2 MFLOPS DP LINPACK
- 10.9 SPEC marks
Memory
Available with 16MB RAM, expandable to 64MB.
- 24 kilobytes DSP static RAM, expandable to 96 kilobytes
Expansion
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.
Troubleshooting
Dimension board LED flash codes
1,2 ROM CRC check failures 3 Bad VRAM 4 Bad NVRAM (The NVRAM store in the clock chip) 5 No usable DRAM
VGA adapter on Dimension
