DSP12DSP.zip
============

DSP12DSP.zip contains the following files for use in conjunction
with V2.00 of the toolkit for DSP-12:

dsp12dsp.txt	-	this file
dspfiles.asm	-	a source files that asssembles to 'dspfiles.obj',
			a constituent file for DSP-12
dspfiles.txt	-	a description of 'dspfiles.asm' and how to use it
howto.txt	-	hints on how to remove modems from DSP-12
lod2data.c	-	a program to convert DSP56001 modem files from the
			.lod format to source text format compatibel with
			'dspfiles.asm' (compile with the 'compact' memory model
lod2data.exe	-	a compiled version of the above.


DSP-12 'liberated'
=================

I have been working with the DSP-12 toolkit for a while and in the 
course of actions I decided that it was about time to make it possible 
to add and remove modem files from the DSP-12.

I have brought the file 'dspfiles.obj' - which holds the code for all 
the DSP modems - onto such a form (assembly code) that it is possible 
to edit it using a text editor. In addition I have written a small 
program that will take the  output from the DSP56000 assembler (the 
.lod file) and bring it on the same form. meaning that new modems may 
be added to the DSP-12.

Please observe that most of the individual DSP modems are still 
available in binary only as released by L.L.Grace. I have no intention 
to or possibility for bringing these files onto assembly format.

The above has the following advantages:

1)	You may reduce the number of options presented on the menu to 
	just the modems you are interested in. In my case I removed 
	everything except the satellite modems, the signal generator 
	and the pipe modem. This gives a very clean menu and it will 
	also give you space for your own developments.

2)	You will be able to burn PROMs which include your own 
	developments. This gives a much faster start-up time than 
	having to download a particular modem every time you need it.
