This brief introduction should have given an idea of what RTM's are, how they operate, and how they are used. It is highly recommended if the reader is planning on physically using these modules, that he first construct the above system in order to become familiar with the modules, conventions, etc. This would be subject to the reader's own prewired Bus conventions. Having gone this far, we are now in a position systematically to describe RTM's in detail. This is done in the next major section of this chapter.

THE RTM SYSTEM

Introduction

The RTM system is a set of about 35 different modules, plus a method of interconnecting modules via a common Bus that transfers data from module to module. This Bus also carries timing signals to interlock the register transfers -- thereby making the system timing independent. For a given system, some of the modules connect to the Bus in order to transfer data; this combination constitutes
