CHAPTER 4
ADDING COMPATIBLE PRODUCT
If you look back at the block diagram of a typical System 310 (Figure
1-2) you will see the system broken down into functional blocks. This
chapter provides the list of circuit boards that you can substitute for
each block when constructing a system. The functional blocks
covered as sections in this chapter are listed below:
• Processor boards
• Processor-specific expansion boards
(shown as the Memory block on the processor board and the
boards on the iSBX bus)
• Disk controllers
• Tape controllers
• Memory boards
• Communication controllers
While the last chapter presented some general guidelines for
integrating new hardware into a preconfigured System 310, this
chapter presents board-specific guidelines. For each board listed,
sections in this chapter specify whether or not you will have to do
anything special to the board or your system to make them work
together. If the board needs no modificaton, that is noted. On the
other hand, if you must make a modification, this chapter points out
whether it is a jumper change or a component change, and tells you
where you can find more specific information.
COMPA IBLE PROCESSOR BOARDS
The processor board characterizes the System 310 in two ways: by the
software it executes and by the performance of the hardware. The
processor governs the type of software that you can run. For example, a
single-user, 86-based system running the iRMX" 86 operating system
acts quite differently from a multiple-user, 286-based system running
the XENIX * operating system. The processor board also governs the
performance of the hardware, including its operating speed and the
number and kind of I/O ports available.
You can buy or build a System 310 around either the 86/30 or the
286/10 processor board. The primary difference between these
boards lies in the CPUs they use. Other hardware differences are
listed in Table 4-1.
