1.0 INTRODUCTION.
The Processor (8080A-2) Module functions as the main controlling unit
fOr the terminal. The processor fetches instructions from memory ana
performs I/O operations on other modules attached to the terminal data
bus (BaCKplane Assembly). The Processor (8080A-2) Module has the capa-
bility of accessing either the standard backplane bus or a special top
plane bus d~fIned later.
2.0 OPERATING PARAMETERS.
A summary 01 operating parameters for the Processor (8080A-2) Module
is contained in tables 1.0 through 5.1.
