Introduction
The IBM 5280 is a diskette-based system. It includes
several data stations and programmable units that can be
connected in a variety of configurations. The
programmable units contain the microcode needed for
the system to operate. There are several devices that
attach to the data stations and the programmable units.
DATA STATIONS
IBM 5281
The IBM 5281 is a tabletop data station that has one
keyboard and one display assembly. The IBM 5281
must be connected to one of the programmable units
before any function can be performed. A maximum of
two diskette drives can be housed within the IBM 5281.
Specifications
• Display sizes are 480, 960, or 1920 characters. All
displays on a system must be the same size.
• Storage is located in the programmable unit to which
the IBM 5281 is attached.
• Keyboards available are data entry, data entry with
proof arrangement, and typewriter.
Theory
• Diskette drives available are the 31SD and the 51TD. No
diskette drives are required in the IBM 5281; however, a
maximum of two diskette drives can be installed.
• One magnetic stripe reader can be attached, but it
is not required.
IBM 5282
The IBM 5282 is a tabletop dual data station that has
two keyboards and one display assembly. The display
image is divided by mirrors to provide a separate display
image for each operator. The IBM 5282 must be
connected to one of the programmable units before any
function can be performed. A maximum of two diskette
drives can be housed in the IBM 5282.
