I. Introduction

This directory contains a Forth implmentation for the TI-980 computer.

Prerequisites:

   asm980 - 1.1.0
   sim980 - 1.1.0


II. To build:

   $ make

This will assemble the Forth source.


III. Files in this directory

   forth.asm        - Forth source
   forth.cfg        - Forth configuration
   forth.lst        - Forth listing
   forth.obj        - Forth object
   forthdat.fpy     - Forth data disk (screens)
   Makefile         - Makes Forth
   README.txt       - This file


IV. How to run

To run the TI-980 Forth:

   $ sim980 -c forth.cfg
   TI 980 Simulator VERSION: 64K

   TI-980 FORTH 1.0.1


The configuration file, forth.cfg, contains:

   a d0 1 forthdat.fpy
   a pr 5 print.out
   l >100 forth.obj

To terminate you enter the command break character, CTRL-E, which puts the
simulator back into command mode, and enter the "q" command to terminate.


V. Known problems/limitations

1. Forth was hacked from the TI-990 version and there may still be issues with
   byte vs. word addressing.
