FORCE Computers 32 bit CPU Board Introduction
The range of FORCE Computers 32 bit CPU boards is one of the most comprehensive and complete available today. Products for all your top end per-formance and versatile functionality needs are of-fered. State of the art technology enabling multi-processing features. True continuous 68020 zero wait state performance at all commercially avail-able frequencies. The cross pollination of the Intel World to the to the VMEbus with the CPU-386. Plus the ability to deliver as promissed with a relentless eye for quality. All these are features that have made FORCE Computers the market leaders in high performance CPU boards.
General Feature Overview
If you are considering a 32 bit CPU board, then it is clear that performance is of importance. When FORCE designed their family of 32 bit CPU boards then maximum performance was crucial in the spe-cification of the product. No tradeoffs were made at the expense of performance.
The SYS68K1CPU-21 board is the first example of this design philosophy. The product is available as a two board set, one board containing the VME-bus interface, CPU and control logic and the se-cond board containing the high speed static RAM.
The two boards are connected via the FLME inter-face. The board set is available with 12.5 MHz, 16.67 MHz, 20 MHz and 25 MHz CPUs and with the 68881 floating point co-processor up to 20 MHz.
The board supports continuous no wait state oper-ation at all frequencies up to 25 MHz from up to 4 Mbyte of local static RAM. The board is also pro-vided with a real time kernel installed as standard.
Additionally, newly available is the SYS68K1CPU-29 which is totally software and hardware compa-tible with the CPU-21, with the exception that the maximum memory capacity is only 1 Mbyte. The CPU-29 is available on one board. For SIW compa-tible upgrades to the memory managed 68030 en-vironment , FORCE Computers has again shown its commitment to their customers by producing the SYS68K1CPU-32. The board is fully slw ompa-tible to the CPU-21 and the CPU-29. The CPU-21, the CPU-29 and the CPU-32 are the 32 bit perform-ance standard.
The SYS68K1CPU-22 provides a complete multi-processing package. The CPU-22 family has a VMX interface to provide the systems integrator with ac-cess a subsystem bus for local memory and peri-pheral extension. Features of the family include the 68020 processor running continuously without the insertion of wait states from the on board dual por-ted static RAM. Revolutionary inter processor communication facilities such as programmable single or group processor interrupts with automatic

programmable vector generation. Intelligent pro-grammable interrupt prioritisation. 30 Mbyte/sec DMA controller. Two serial 110 channels. On board real time kernel in EPROM. All provided as standard.
The CPU-22 is the 32 bit multiprocessor solution.
SYS68K1CPU-25 offer a 32 bit memory managed environment that sets new standards in the micro-computer world. Running with a single wait state from up to 4 Mbyte of local memory through the PMMU (68851), the board provides the perfect base for perform ace applications that need me-mory protection. Application areas are multi user workstations and UNIX environments. The CPU-25 are the performance memory management solu-tion.
If it's general purpose features that you want with your 32 bit processor board, then look no further than the SYS68K1CPU-26 family. The boards come with up to 4 Mbyte of dynamic RAM inducing only 1 wait state on the 68020 at 20 MHz. The boards also come with 4 serial 1/0 channels and a SCSI bus interface and a floppy interface. In addition, all the comprehensive multprocessing and DMA features offered by the 22 are also offered by the CPU-26 family. The CPU-CPU-26 is the versatile solution.
For those systems integrators who have invest-ments in Intel SIW and experience in Intel environ-ments, FORCE Computers has the answer. The SYS80KlCPU-386 is the first implementation of the 80386 processor on the VMEbus. The board pro-vides as standard 2 Mbyte of DRAM, 3 serial 1/0 channels, a full VMEbus interface with slot 1 func-tions and the facility for the insertion of the 80387 floating point co-processor. This board is the VME-bus-Intel solution.
