AMOS was written for the Commodore Amiga in 1989 by Francois Lionet, based on STOS, an unsuccessful language for the Atart ST. It featured high-performance graphics and sound manipulation facilities and put the ability to program full games into the hands of the home-user.
It was first released by Mandarin Software, and in 1992, Mandarin released two packages to boost functionality - AMOS 3D and AMOS - The Compiler.
The Compiler added the ability to build entirely AMOS-independent programs, which could remain on a disk without the need for the cut-down run-time system, RAMOS.
In late 1992, development showed further results when Europress Software released AMOS Professional. This product was far better thought out than its predecessor, since all the bundled tools were well organized and logical. It also received the highest score for software (97%) in reviews in Amiga Format magazine.
Later, Several add-ons have also been created, most notably the GUI Add-On, which allowed, for the first time, support for the native Amiga operating system, something lacking in earlier versions.
What It Can Do
AMOS Professional is still used today for simple programming, mainly by Amiga enthusiasts and by emulation fans.
There appears to be no official site, though Clickteam, who Francois now programs for, have the official source code on their site ( www.clickteam.com ) and have made the Amiga Disk Files, suitable for emulation, available to the public at no cost at Back To The Roots ( www.back2roots.org ).
