DOS is a general acronym for "Disk Operating System", though it came to refer to the operating system used in the IBM PC, particularly Microsoft's MS-DOS.

While the very first computers did not have operating systems, the lack of them made computers less efficient and more difficult to use. We look at the general history of operating systems before getting into the history of DOS. Then we look at some general principles of what operating systems do.

Love this history

Thank you for sharing this info. It is so much fun learning the history and challenges we take for granted behind today's technology.

It reminds me of the PBS 3 part documentary "Triumph of the Nerds"

Keep up the awesome work.

You are most welcome

Ultimately klaatu is the person who got this going. This material was on my web site for over 20 years when he asked to use it for That got me to ask Ken if he thought HPR would like it. But I guess it shows the value of having your own web sites and controlling your own content.

Audio quality

I don't know what problem you found with the MP3 file, but it was not on the original. I upload a FLAC file to HPR, which is then converted into other formats for downloading. I subscribe to the OGG feed, and just listened to the show on that feed, and there was no problem. So either there was a glitch in the conversion to MP3, or you had some issue with the download.

Can you define broken

Hi Jan,

I checked all the files and I can't find anything odd.

Can you give me more information please.
