I send you 3 example machine code programes:

AUTORUN  LIS -  make your NC autorun a program
I2C      LIS -  use the I2C-bus with your NC
ROMCOPY1 LIS -  for save the NC firmware ROM to files
ROMCOPY2 LIS -  for save the NC firmware ROM to files
SCN2FILE.LIS -  for save and redraw the NC screen.
SCNGRAB .LIS -  for grab a part of an screen shot file.
WIN2FILE.LIS -  for save/redraw only a part of the screen.
CLOCK    PIC -  a screen grab (you can redraw with WIN2FILE).
DOCS     PIC -  a screen grab.
MAIN     PIC -  a screen grab.
NOTEPAD  PIC -  a screen grab.

AUTORUN.LIS
-----------

Start a BBC BASIC program when you switch on your NC. AUTORUN is more 
usefull you may think! In this way you can start your NC with the build in 
alarm clock (ones in a year or dayly, what ever...) and start a autorun 
program to do a work automaticly and switch of the NC when finish.


I2C.LIS
-------

Do you know the I2C-bus (or IIC-bus)? It is the Inter-IC-bus and needs only
two wire for communication. A lot of IC's like digital I/O's or DA- and AD-
converters use this bus. (In the next time the electronics magazine ELEKTOR
publishing my article of a 8-bit-I/O-I2C-bus-modul) 

You can control the I2C-bus with the printer port of your Amstrad NC very 
easy by using this program and and a minimum of hardware (only two 330 Ohm 
resistors):



                   Amstrad NC               I2C-bus
                  printer port
                  SUB-D25 male          Mini DIN 6 male

                          |
         SCL In    10 o---+

         SDA Out   9  o---o-----[R330]-----o  5 SDA
