I. Introduction

This directory contains a Forth implmentation for the TI-990 computer.

Prerequisites:

   asm990 - 2.0.8
   sim990 - 1.6.4


II. To build:

   $ make

This will assemble the Forth source. 


III. Files in this directory

   forth.asm        - Forth source
   forth.cfg        - Forth configuration
   forth.obj        - Forth object
   forth.lst        - Forth listing
   forth.prc        - Forth DX10 SCI procedure
   forthdat.fpy     - Forth data disk (screens)
   forthsrc.fpy     - Forth source disk (TX-990 format)
   forthsys.fpy     - Forth system disk (bootable)
   Makefile         - Makes Forth
   README.txt       - This file


IV. How to run

To run the TI-990 Forth:

   $ sim990 -c forth.cfg
   TI 990 Simulator VERSION: /4 CPU 56K

   9900 FORTH 1.0.2


The configuration file, forth.cfg, contains:

   a p >40 4 forth.out
   a f0 >80 7 ../disks/forthdat.fpy
   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

None known.
