Geek Fact for July 19th – It’s All About IBM

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.

  1. I still have these on 5 1/4″ Floppies!! They were with my first IBM computer – a Turbo Laser with dual floppies and 512 KB of RAM that I got at Sears with my very first charge card!! I later put in a 20 MB (that’s right MB not GB) full height hard drive and upgraded the RAM to 640 KB with a 128 KB upgrade kit! I also still have all the word processor and game software (I have the CGA version of Paperboy, the Kings Quest Series, and Police Quest series) on the 5 1/4″ floppies too – a whole big disk box that I never could get rid of it. They are probably considered classics by now!
