IBM 3174 Introduction

3174 Model 63R
The 3174 Model 63R connects to the IBM Token-Ring Network. It contains a Type
3A Communication
Adapter that provides the ability for the controller to operate on
an
IBM Token-Ring Network at either 16Mbps or 4Mbps. When connected to a
Model 63R, terminals can be located almost anywhere within an establishment and
still operate at near channel response time.
The
Model 63R has 2MB base storage and one 5-1/4-inch, 2.4MB, high-capacity
diskette drive.
If the controll~r has one diskette drive and uses devices that
require downstream load microcode, a second diskette drive or fixed disk must be
installed. A nine-port terminal adapter supports nine terminals directly or sixteen
3270 terminals and eight ASCII terminals through one or two IBM 3299 Terminal
Multiplexers.
Customizing is performed with a control unit terminal attached to port 0 of the 3174.
Any terminal can be attached to port 0 at other times. The Model 63R supports full
keyboard utilities.
Subsystem online tests and problem determination are performed through a
control unit terminal attached to any port or multiplexer without interrupting other
terminals attached to the 3174. Offline tests are performed through the 3174
control panel.
The customer can install the following features on this model:
Second diskette drive
Storage Expansion
Asynchronous
Emulation Adapter
20MB Fixed Disk Drive
