Emulation of the ICL 1900

We have now released the source code under GPL and it can be downloaded from here.
There is also a precompiled system for Win32 PCs here.
To make a version to run on another system, start with the PC version and replace all the .exe files with versions compiled from the GPL source.

We also have a version pre-packaged to run the ALGOL68-R compiler, the first compiler for Algol68 in the world. This system can be downloaded from (2.9 Mbytes)


There is a scanned PLAN Reference Manual:

Source text

The source text of George3 is here.

We do not have the George 3 macros on-line, or the Programmer's Reference Manual (PRM).
We do have the PRM on micro-fiche, and hope that some day technology will be available to us that will enable us to put the material on-line.


N.B. You are not allowed to make any commercial gain from this system, which is rather at the level of a-test.
Multiple attempts have been made to contact people who might be copyright owners, but without success. We did get clearance years ago to use the material for academic study. It is hoped that your interest is of that nature.

If you feel that any of the material here is inappropriate, please make contact.
