powerup and RESETs.

     The OS makes temporary use of locations 36876 to 36896 ($900C to
     $9020) to set up vectors for the interrupt handler. See the OS
     listings pages 31 and 81. This code was only used in the
     development system used to design the Atari.

CARTRIDGE A: 8K

Locations 40960 to 49151 ($A000 to $BFFF) are used by the left
cartridge, when present. When not present, this RAM area is available
for other use. The display list and the screen display data will be in this
area when there is no cartridge present.

Most cartridges use this slot (see above) including the 8K BASIC,
Assembler-Editor, and many games. Below are some of the entry
points for the routines in Atari 8K BASIC. There is no official Atari
listing of the BASIC ROM yet. Many of the addresses below are listed
in Your Atari 400/800. Others have been provided in numerous
magazine articles and from disassembling the BASIC cartridge.

STATEMENT name table. The statement TOKEN list begins at 42161
($A4B1). You can print a list of these tokens by:

     5   ADDRESS = 42161
     10  IF NOT PEEK(ADDRESS) THEN PRINT:
        END
     15  PRINT TOKEN,
     20  BYTE = PEEK(ADDRESS): ADDRESS = A
        DDRESS + 1
     30  IF BYTE < 128 THEN PRINT CHR$(BYT
        E);: GOTO 20
     40  PRINT CHR$(BYTE - 128)
     50  ADDRESS = ADDRESS + 2: TOKEN = TO
        KEN + 1: GOTO 10
