ml1.org.uk Implementation on Digital PDP-11 under DOS/BATCH

Overview

Hardware platform Digital PDP-11
Operating system DOS/BATCH
Author R.C. Saunders
Implementation method LOWL-map
ML/I version AID
Implementation version Unknown

Notes

This implementation was performed at the University of Kent, using the NICE implementation of ML/I.

The PDP-11 was a two-address machine, which made the mapping macros somewhat more complicated; LOWL has a single-address machine model. Mapping was performed from LOWL to PAL-11, the assembly language for the PDP-11.

Available files

This section includes not only program files, but also supporting files such as test suites, etc.

No binaries of this implementation now exist. However, the mapping macros have survived and are of interest due to the nature of the PDP-11 instruction set (see above).

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 http://www.info-zip.org. Clicking on the 'Zip' graphic at the end of this section will take you straight to the main UnZip page.

Available user documentation

Documentation format

Each document is available in Portable Document Format (PDF). This can be viewed on most systems using appropriate software such as Adobe Acrobat Reader, which is freely available from http://www.adobe.com. Clicking on the 'Get Adobe Reader' graphic at the end of this page will take you straight to the main Adobe Acrobat Reader 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.
