The system area variable CGPNT (3 bytes) at #F91F contain the slot id and
the location
of the character set.

#F91F  = Slot Id (normally #00 , ie. in basic rom)
#F920  = Address of character set (normally  #1BBF as mentioned above)

Changing this pointer allows You to define several 8*8 pixel fonts
elsewhere in RAM.

The character set requires 8*256 bytes = 2 Kb if You need all 256 chars.
