SYP-310 (Intel System 3xx)

General description

The System 310 (shown on the pictures above) is a versatile, stand-alone microcomputer system, designed to provide low-cost 16-bit computing power and Open System versatility for original equipment manufacturer (OEM) applications. It offers a selection of operating systems, processors, and mass storage devices. The industry- standard MULTIBUS® system bus (IEEE-796) and extra board slots allow hardware to be easily added to the system to support specific applications.

OPEN SYSTEM SUPPORT

The design of the System SYP 310 exemplifies Intel’s Open System concept of allowing OEMs to add value to the system in any of the following three ways:

  • Adding the most recent as well as future generations of VLSI microcomputers
  • Taking advantage of industry-standard hardware and software, both from Intel and independent vendors
  • Integrating OEM-designed hardware and software into the system at any level (system, board, or component)

To support this Open System concept, Intel offers the following hardware and software modules for use in the System 310.

PROCESSOR

The processor board or use with the System SYP 310 is the iSBC® 286/12 processor board, based on the Intel 80286 microprocessor. For increased processing power, you can add an 80287 floating-point math coprocessor to the board.

OPERATING SYSTEMS

Intel offers a choice of two industry-standard operating systems for use with the System 310: Intel’s iRMX™ Operating System and Microsoft’s XENIX* Operating System. Both of these operating systems are powerful vehicles for developing and supporting applications programs or for running off-the-shelf iRMX- or XENIX- compatible programs.

DISK DRIVES

The System 310 chassis provides space for two 5i-inch disk drives. These spaces can be filled with one or two double-sided, double-density diskette drive and a Winchester hard disk drive.

CHASSIS

The attractive, low-profile chassis for the System 310 is 17 inches
wide, 6% inches high, and 20 inches deep, and weighs 40 pounds. It
contains a power supply, cooling fans, and a seven-slot cardeage.

DIAGNOSTICS

A monitor program and a set of diagnostie programs, located in PROMs, are included with the System 310. These programs provide start-up diagnostics for verifying that the system is operating correctly. An additional set of diagnostic programs, some provided on a diskette and some with the operating system, can be used for troubleshooting and fault isolation.

MULTIBUS BORDS IN MY SYP-310

The SBC 80/10’s system bus structure permits interfacing to one other Multibus-Compatible Master module. This interface is accomplished using the serial priority scheme using the Intel SBC 604 Cardcage/Backplane.

The SBC 80/10 does not provide the Bus Priority Request Out (BPRO/) signal and therefore, the SBC 80/10 can only be used with one other Multibus master. For these configurations, the SBC 80/10 must always have lower priority than the other Multibus master and a wire must be added from the master’s BREQ/ pin (pin 18) to the SBC 80/10 BPRN pin (pin 15). The SBC 80/10 acquires control of the Multibus whenever BREQ/ generated by the Diskette Controller is in the high state. This occurs whenever the Diskette Controller is not using the Multibus. Similarly BREQ/ is driven to the low state when the Diskette Controller acquires control of the Multibus disabling the SBC 80/10 from accessing the Multibus.
For a detailed description of Multibus interfacing refer to the Intel Multibus Interfacing Application Note (AP-28).
