Here is part two of the c64 kernel memory map series.  Like last time, sub-
routines in capital letters are described in the "Programmer's Reference
Guide".  (But the only sure way to know exactly what they do is to look at the
code.)  Do not call them at these addresses, however!  Due to slight variations
between different versions, they may float around a tad.  Instead, use the jump
table addresses provided in the PRG.  This map is intended only to aid you in
disassembling and understanding the code.

E8DA  color code table
E8E2  code conversion

EA24  synch color to character
EA31  UDTIM  (IRQ comes here)
EA87  SCNKEY
EB59  set text mode
EB79  keyboard vectors
EB91  keyboard maps
EC44  graphics/text control
EC4F  set graphics mode
ECB9  VIC chip initialization table
ED09  TALK

EDBE  clear ATN
EDC7  TKSA
EDDD  CIOUT
EDEF  UNTLK
EDFE  UNLSN
EE13  ACPTR
EE85  clock line on
EE8E  clock line off
EEB3  delay 1 ms

To be continued.
