This collection of pages provides information on IBM's SMS (Standard Modular System) cards. These transistorized cards were the technology behind IBM computers from the 1950s to 1970s such as the IBM 1401, IBM 1620, and IBM 7000 series.

There are thousands of different types of SMS cards. Information on them is scattered across many old documents and hard to find. I have collected information on 1225 SMS cards on these pages. Click on a card code for more information.

If you have photos or SMS documents to contribute, please contact Ken Shirriff.

The information on these pages comes from a variety of sources, especially old IBM documents on bitsavers.org, as well as information from the IBM 1401 restoration team, especially Tim Coslet's SMS data and Jim Hunt's data. Much of this information was obtained through OCR, so don't expect complete accuracy. These pages are not associated with IBM in any way.
