Introduction


Welcome to Computer History Museum's web site on the IBM 1620 Data Processing System. It is our goal to make this the most accurate and authoritative site on this computer in the world.

Two thousand of these computers were built in the 1960's. Due to its unique characteristics, convenient small size and relatively affordable price many of these machines were bought or rented by colleges and universities. As a result, hundreds of thousands of students had their first hands-on computer experience with the IBM 1620.

Like first love, this experience made a lasting impression on many people. Ask any seasoned computer professional and there's likely an IBM 1620 in their past.

Unfortunately, few of these machines survive today. They are in museums or private collections and recent computer science graduates are generally unaware of the machine and its place in history.

That's the purpose of this web site (and in fact the reason that Computer History Museum exists) -- to preserve the physical machine and the computer technology it incorporates; to capture the history which surrounds it; and to share that with the world.

Most of the people involved with the development, manufacture and use of the IBM 1620 are still alive. We've captured some of their knowledge and memories in these web pages and look forward to hearing from others.

Which is the last point to be made. To the best of our knowledge, the information contained in these pages is accurate but incomplete. Please help us improve this site by contributing your piece of IBM 1620 history.

We hope that you enjoy this site and learn something about this historic computer.
