Service Manual
Included in the following pages are instructions for
installing and interconnecting the Multiterminal Interface
PCB in the Model 16 Radio Shack Computer. This option
allows you to interconnect as many as five additiona1
terminaIs to the computer so that a common data base may be
used by aIl terminaIs. Refer to the TRS-XENIX Operator's
Manual for operating instructions for the system.
2.1. Software Requirements
The only current operating system offered by Radio Shack
which supports this board is TRS-XENIX, Version 01.03.00 or
higher. You must upgrade your system to at least a version
01.03.00.
If you already have the XENIX Operating System, it is
necessary to modify it using a software update diskette
(Catalog No. 700-2066) which modifies a 1.1 or 1.2 system to
a version 01.03.00 System.
If you do not have the XENIX Operating System, it will be
necessary to purchase the XENIX Version 01.03.00 Core System
(Gatalog No. 700-2052).
2.2. Installation
The following instructions are given to allow proper
installation of the Mu1titerminal Interface Board, check out
its function to ensure proper operation, and perform
modifications required to the Main Terminal to al10w
communication between it and the remote termina1(s).
The Multiterminal Interface Board is installed in a Model 16
or 16B in the card cage assemb1y. It is accessible when the
rear cover is removed from the Model 16B Case Assemb1y, or
the top cover from the Model 16.
