Dear Amstrad NC user,

the new version of NC100 Disassambler includes string search and 
banking! So now you can look to the hole NC100 memory (RAM, ROM, 
card-RAM).

In  prevention  of  data lost backup any files on your NC before 
running the disassembler!

Start  the  disassambler only by starting DISSTART witch set the
variables PAGE to &6000 and  LOMEM to &9000 and then calling the
DISASM programme. This  is  for  makeing room to banking in a 16 
Kbyte block.

The  picture  below shows the memory map of a NC under the BASIC 
programme DISASM calling from DISSTART:

       +----------------------+----------------------+ &FFFF
       |    16 KByte ROM      |  4 KByte screen RAM  |   
       |  BASIC-Interpreter   +----------------------+ &F000
       |                      |
       |                      |
       |                      |
       +----------------------+ &C000    
       |   Operating-System   |
       |   stack and memory   |
       +----------------------+ &A000 = HIMEM 
       |   8 KByte RAM used   |
       | for BASIC variables  | &9000 = TOP and LOMEM
       +----------------------+ &8000     
       | 16 KByte normaly RAM |
       |                      |
       +     memory area      + &6000 = PAGE 
       |                      |
       | used for banging in  | 
       +----------------------+ &4000
       |        memory        |
       |       not used       |         
       |                      |
       +----------------------+ &1300     
       | BASIC-stack / memory |
       +----------------------+ &0000 

The 4 Kbyte screen memory of the NC100 is  under  the  BBC BASIC 
interpreter  at  the  end of memory from address &F000 to &FFFF. 
You can look for it with  the  disassamber  by  banking 16 Kbyte 
RAM-bank  3  to  location  &4000 - &7FFF. The screen memory must 
then appear from &7000 to &7FFF.  Look my  "BBC BASIC reference" 
and  "The Low Level Operation Of Amstrad Notepad Computers"  for 
more information. 

And  now  I  have  a  great request to you: Please tell me of all 
what you found in the memory of your NC!
