Radio Shack Telephone Interface II Operation Guide

INTRODUCTION
The Radio Shack ® TRS-80® Network 3 Controller enables educators to design a
network of
up to 16 non-disk TRS-80 Model III microcomputers (or Student
Stations) around one TRS-80 Model III disk Host system.* The Network 3 provides
the Student Stations with most of the capabilities of a disk-equipped computer
system. For example:
• All 16
Student Stations can load and store programs and other information
using the disk at the Host system.
• All Student Stations can use a line printer attached to the Host system
without interrupting other students or the teacher.
•
Student Stations can store information on the Host disk, allowing class
records
to be kept in one location.
• Network 3 even
makes it possible for computer science students to learn and
use Disk BASIC on non-disk TRS-80s.
In addition to being a part of a network, each participating TRS-80 Student Station
can also be used as an independent, stand-alone unit. This flexibility helps to make
the Network 3 an ideal choice for classroom or administrative purposes.
The Network 3
system in its maximum 16 Student Station configuration is most
suitable for situations where there is moderate-to-infrequent student interaction with
the Host computer (that is, loading or saving programs, reading or writing disk
data files, or accessing the printer). Where a higher frequency of student interaction
with the Host is desirable, smaller configurations (fewer Student Stations) may be
appropriate depending on
your particular application. If you have questions about
the best configuration for your application, contact your Radio Shack Regional
Educational Sales Coordinator or a Radio Shack Store or Computer Center
near you.
* Future Network 3 Software will support the TRS-80 Color Computer as Student Station
and the TRS-80 Model II as Host.
