MS DOS Programming Systems
Forth IDE for DOS applications, particularly suited for x86 embedded PC development. Holon86 is also useful for studying Forth, both the language (all words of the application system are presented in the browser) and the inner machine (single step through the program down through the kernel and 'next').
Holon86 was my main development system, both for developing client projects and to create the other DOS Holon systems.
Forth IDE for 68HC11 micro controllers. Holon11 proved useful for teaching microprocessor programming, due to its interactivity and its facility to single step through machine code.
Forth IDE for the Java virtual machine (JVM).
Universal source handling tool.
The systems still work fine in a DOS Box.
