New I/O devices for the Model 165 are:
• The 3330 facility - attaches only to a block multiplexer channel
• The 2305 facility Models 1 and 2 - attaches only to a block
multiplexer channel
• The 3211 Printer - attaches to any Model 165 channel
• The 3803/3420 Magnetic Tape Subsystem - attaches to any Model 165
channel
The 3330 and the 2305 facilities represent significant advancements
in direct access device technology. They provide larger online data
capacity and faster data rates and access than heretofore, as well
as expanded error correction features. Both have rotational position
sensing and multiple requesting as standard features.
The 3330 represents the latest direct access device with removable,
interchangeable disk packs. It embodies new data recording and access
technoloy~. The 2305 facility is a major extension of the nonremovable,
high-speed, fixed-head direct access storage concept.
The 3803/3420 Magnetic Tape Subsystem incorporates all the latest
advances in tape speed, design, and technology. It offers new features
and enhanced reliability, availability, and serviceability to 2400-
series magnetic tape users.
The major new characteristics of the 3330 and 2305 facilities, the
3211 Printer and the 3803/3420 tape subsystem are discussed in the
following subsections
