>>> TurboForth.net <<<

TurboForth.net is the companion web site for the TurboForth system written in TMS9900 Assembly Language by Mark Wills for the Texas Instruments TI-99/4A computer.

TurboForth Features

Fast - most of the words in the TurboForth vocabulary are written in TMS9900 Assembly Language for the fastest possible execution speed
Compact - produces some of the most compact, memory efficient code possible on the TI-99/4A
Complete - Hosted on a plug in cartridge. TurboForth is a complete, self hosting language. No need to load it from disk, occupying valuable memory space
Feature Rich
- 40 Column mode
- 80 Column mode
- 32 Column mode
- 32 Sprites
- Speech supported (speech synthesizer required)
Numerous support packages available:
- 32 bit (including pictured numeric output)
- Floating point
- TMS9900 Forth assembler
- Local Variables
Free - Image files for PC-based emulators are completely free. Plug in cartridges are available for a nominal fee to cover cost of the EPROM (non-profit)

This Site

Since the TI-99/4A cannot realistically support an on-line help system, this site has been created to document all the features of TurboForth. Quite literally an online-help system! All the Forth words available in TurboForth from power-up are documented here with examples, stack signatures etc. There is also a section on what the Forth language "is" for new-comers to the language. Technical information, such as the memory map are also available, in addition to numerous support libraries. Source code is available to browse online, in addition to a downloadable archive.

Contact

If you want to communicate with other Forth-minded individuals (there's more of us than you think!) then comp.lang.forth is a good place. If you want to communicate with TI-99/4A Forth nerds (or just TI-99/4A nerds/programmers/fans in general, then I and a bunch of others hang out on the really cool TI-99/4A Development pages over at Atariage.com - yes, a website ostensibly dedicated to Atari machines, but which (very kindly) hosts a TI-99/4A forum for us nerdy types.
