System 310
Overview
As an example of how to use the block diagram, suppose you want to
add a processor board to your system. First, you would find the block
labeled "Processors" in the diagram. You can see that you must
choose a MULTIBUS-compatible board because Figure 1-2 shows the
processor module connected to the MULTIBUS® interface. You also
see that processors can communicate with any other module
connected to this bus. Other boards can communicate with the
processor over two additional buses: the iLBX " bus (286/10
processors only) and the iSBX " bus. In addition, the processor may
contain firmware and on-board memory.
To chose a specific board, refer to Chapter 5 in this manual. Chapter
5 tells you that the processor block may be either the iSBC® 86/30
Single Board Computer or the iSBC 286/10 Single Board Computer.
Furthermore, it lists the names of all the iSBX expansion boards that
are compatible with each processor.
S ANDARD SYS EM 310 CONFIGURA IONS
Intel offers several preconfigured versions of the System 310. Each
one contains many of the hardware modules in Figure 1-2. These
systems fall into two categories, based on the kind of processor they
contain. Specifically, three configurations are designed around the
8086 microprocessor; two others are designed around the 80286
microprocessor.
HREE 86-BASED CONFIGURA IONS
The three 86-based configurations of the System 310 share several
features. They are:
• 7-slot MULTIBUS cardcage
• 86/30 processor board
• RS-232 serial port
• Parallel port for a Centronics -type printer interface *
• 5i-inch flexible diskette drive and controller
• 220-watt switching power supply
In addition to this hardware, common to each preconfigured system,
each preconfigured version also contains configuration-specific
hardware which appears in the following lists. In general, the
preconfigured systems differ by the number of unused card slots, the
amount of Random Access Memory (RAM), the type of disk storage
provided, and the presence or absence of hardware support for
floating-point math.
System 310-1 Configuration-Specific Hardware
• 6 unused card slots
• 128K bytes of RAM
