IBM 3174 Introduction

3174 Model13R
The 3174 Model 13R is designed to connect to an 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. It
has 2MB of base storage and one 5/1.4-inch, high-capacity diskette drive. If this
controller is shipped with Configuration Support-A or -S, Release 5, the diskette
drive is 1.2MB. If the controller is shipped with Configuration Support-B, the drive
is 2.4MB. If the controller has one diskette drive and uses devices that require
downstream load microcode, a second diskette drive or fixed disk must be
installed. A four-port terminal adapter that attaches
