Abstract

The IBM Word Processor/32 (Fig. 1) includes an IBM System/32 processor and other units. In one version, the System/32 is enhanced with (a) upper/lower case keyboard and display, (b) printer half indexing for superscripting and subscripting and (c) printer upper/lower case. In another version, System/32 is enhanced by an additional capability for processing standard IBM magnetic cards as input and output media. This capability is in a stand-alone attachment, the IBM Type 5321 Mag Card Unit (MCU). The system takes advantage of the processing power, software, etc., of the System/32, and offers features and capabilities normally characterized as "word processing" or "text editing".

Word Processing System with Magnetic Card Unit

The IBM Word Processor/32 (Fig. 1) includes an IBM System/32 processor and other units. In one version, the System/32 is enhanced with (a) upper/lower case keyboard and display, (b) printer half indexing for superscripting and subscripting and (c) printer upper/lower case. In another version, System/32 is enhanced by an additional capability for processing standard IBM magnetic cards as input and output media. This capability is in a stand-alone attachment, the IBM Type 5321 Mag Card Unit (MCU). The system takes advantage of the processing power, software, etc., of the System/32, and offers features and capabilities normally characterized as "word processing" or "text editing".

The following describes a typical operating sequence for the system.

Assumptions:
1. It is assumed that the system has all components including the

MCU, which is shown in greater detail in figs. 2 and 3.
2. Magnetic Cards have been recorded on an IBM Mag Card I

SELECTRIC* typewriter or an IBM Mag Card II System.

a. The cards contain necessary information for preparation

of a form letter.

b. One of the cards has all names and addresses (variable

data of recipients of letters.

Operation:
1. Operator depresses Start button 10 (Fig. 3); Ready lamp comes

on.
2. Operator loads cards in feed hopper of MCU, also referred to

as Mag Card Reader/Recorder (MCR/R).
3. Operator installs a diskette 2 in the System/32 having program

for controlling preparation of the letters.
4. Operator initiates "program load" from keyboard 3.
5. System initiates reading of magnetic cards into fixed disk 4

or diskette 2.
6. System/32 processor merges variable data into form letter and

formats letter under application program control.
7. Output is complete form letter either (a) printed at

approximately 80 lines per minute on the System/32 printer 5

or (b) output onto magnetic cards for printing on the Mag Card

I or II SELECTRIC typewriter.
8. Operator removes letters from printer and magnetic cards

from MCU stacker.

For the following discussion it is assumed that the form letter and names/address cards have been put in the hopper of the MCU, that the program has been loaded responsive to keyboard initiation, and that the program is now in full control of system operation. Read Cards. Signals are picked up by a read/record head in the Mag Card Unit 1 (there being separate gaps on the head for reading and recording), amplified and passed to a read/record control which will be in the read mode. Signals are then passed to a channel interface where they are formatted into a data block which is passed to drivers and then through the interface cable to the System/32 adapter. The data enters the adapter via a

receiver and is funneled into the data bus in (DBI) assembler and buffer. From there the characters, 8 bits at a time, are routed to the basic System/32 port and into the System/32 electronic memory, then fixed disk or diskette. P...
