This implementation was the culmination of work by three different people, working at widely separated locations.

More details of this implementation may be found in An exercise in machine independence.

This implementation was later used by Bob Eager to bootstrap a new implementation for the ICL 1900. Without it, the work would have been much more difficult!

Available files

No source files of this implementation now exist. The binary card deck image used to load ML/I has survived; it was used by Bob Eager to implement the later version on the ICL 1900.

File format

Each file, or group of files, is available as a ZIP file (.ZIP). This can be unpacked using the ZIP utility, which is freely available from Clicking on the 'Zip' graphic at the end of this section will take you straight to the main UnZip page.

As an alternative, each document is also available in HTML, as a single file. This can of course be viewed with any browser, although the output is not as pleasing as the PDF version.
