The documentation will be posted to the net as well as available via ftp.
Please do not misunderstand, I do not mind calling and spending the time to
answer questions, return my mail concerning the units, etc.  I just have in
the past read all the messages subjected: More Units... and have usually found
that they are concerning my stupid postscript.  A few dollars here and there
will not kill me.
	You are right though about the undocumented code, it is inexcusable.
My only answer is that there is really nothing I can do except provide the
documentation.  As to the convoluted code...
	The interrupt 33h's are the interrupt to the mouse driver.  I will take
a closer look, but I don't think that they will work quite as well if commented
out.  There is, however, a good chance that I am wrong as I wrote the mouse
unit three years ago and have not touched it much since.  The reason for the
write to low memory is to fool the mouse driver (logitech version 4) that I
have into accessing the rows above 25.  Without convincing the driver that it
is really in mode 3 (80x25) the mouse simply disappears after row 25.  For
graphics that is not needed.
	I am really sorry about wasting all of your (plural) time with the 
`orribly uncommented code; but they ought to work without too much 
modification.
	In the process of documenting I am cleaning up the code considerably,
so that perhaps when I repost everything, you will not be so disappointed...

ciao
