In 1988, International Business Machines (IBM) shipped version 4.00 of the PC-DOS operating system.
PC-DOS 4.0 had an optional text-based file manager shell (DOSSHELL) with pull-down menus called by typing the F10 key, optional mouse support, a text-based user interface and support for hard disk partitions over 32MB.
In 1960, IBM debuted its IBM 1001 Data Transmission System.
The IBM 1000 Data Transmission System answered telephones and recorded messages using punch cards. It allowed you to collect information in a more timely manner. Information could be sent from any office, plant or department for the cost of a phone call.
