Comprehensive Guide to the IBM 1130 Computing System

Welcome to IBM1130.org, the premier digital archive and community hub dedicated to the IBM 1130.

Overview of the System

The IBM 1130 was designed as the most affordable computer in IBM's catalog at the time of its release. It was specifically engineered for technical sectors that required heavy computing power but had limited budgets.

Target Demographics

Market Segment	Primary Need
Education	Accessible computing for students/faculty
Engineering	Intensive technical calculations

While the 1130 didn't necessarily ~~revolutionize~~ break new technical ground, it offered a compelling $\text{Value} = \frac{\text{Performance}}{\text{Cost}}$ ratio. A standout feature was its inclusion of low-cost disk storage, which was a significant advantage for its era.

The 1130 and its various non-IBM clones served as a gateway to "personal computing" for a vast number of early users. Its historical importance stems less from its specs and more from the deep nostalgia and affection held by those who operated it.

Visitor Checklist

If you are new here, we recommend the following:

Try the 1130 Simulator to run legacy code on a modern PC.
Learn about the "11/30" Party, an annual gathering of programmers, maintainers, and developers.
Browse the archives for hardware and software documentation.

Technical Note: Simulation

The simulator allows you to execute code in several languages. For example, a simple FORTRAN block might look like this:

C SAMPLE FORTRAN CODE FOR 1130
      PROGRAM HELLO
      PRINT *, 'HELLO FROM THE 1130'
      STOP
      END
