There are many legions as to how Microsoft got into the
operating system business. Back in 1981 IBM was looking for an operating
system for a microcomputer it was building. In that day, CP/M was more the
operating system of choice. The folk lore, IBM came to Microsoft for their Basic
language, that Microsoft also sold them an operating system that at the time
didn’t exist. This operating system became DOS and has thus evolved since.

If you did deeper, you’ll find that IBM actually asked
Microsoft about an operating system, but Microsoft directed them to Digital
Research. Digital Research had a CP/M operating system that was considered the
one to use at the time. When Digital Research’s leader was not shot up with IBM,
and he saw no reason to do a deal with them. As a result, IBM worked with
Microsoft to see what they could come up with. Microsoft was able to
deliver by purchasing QDOS from Seattle Computer Products. The rest, as they say, is history.

Digital Research bumbled the chance to be the Microsoft
of today. Had they not blown the operating system deal with IBM, Digital Research might be where Microsoft is today.

Other companies have had similar moments of stupidity.
I’m currently reading “In Search of Stupidity” by Merrill Chapman. I’ll end up
posting a review of this book on the Codeguru site. If you are interested in
hearing about some of the stupid decisions computer companies have made in the
past, then this is a book for you. The case of IBM, Digital Research, and
Microsoft is covered in more details. Also covered are a number of
other companies and products that you may have heard about. If you
developed in the 80s and early 90s, then you will definitely find a number of the stories in this book interesting.

I was a big developer of dBase III/III+ applications
many years ago. Having lived through the downfall of Aston-Tate, it was
interesting to get some history about the management decisions that helped drive
the company out of existence. Reviewing the history of companies such as those
in this book can provide insights on how to avoid stupidity in your own company. You can find the book at:,31pz,1,d7xi,ksj4,jorm,i5r0

If you are also reading a good book that would be of
interest to developers, feel free to submit your own review to Codeguru. You can
send a review to me or post it directly on our web site.

Until next week…
