This is the 4th and final note in the c64 kernel memory map series.  I hope you
have enjoyed it.  I've now done two series (floating point and memory map) plus
lots of little notes.  I plan to do some more series on other topics, but
you'll have to wait until summer semester for most of it as I'm just getting
too busy at the moment.

FA60  store characters
FD8E  reset pointer
FB97  new tape character setup
FBA6  toggle tape
FBC8  data write
FBCD  tape write (IRQ)
FC57  tape leader write (IRQ)
FC93  restore vectors
FCB8  set vector
FCCA  kill tape motor
FCD1  check read/write pointer
FCDB  bump read/write pointer
FCE2  cold start (RESET) comes here
FD02  check for auto-start cartridge
FD15  RESTOR
FD1A  VECTOR
FD30  table of vectors for RESTOR
FD50  RAMTAS
FD9B  IRQ vectors
FDA3  IOINIT
FDF9  SETNAM
FE00  SETLFS
FE07  READST
FE18  SETMSG
FE21  SETTMO
FE25  MEMTOP
FE34  MEMBOT
FE43  warm start (NMI) starts here...
FE47  ...and winds up here on default
FE66  BRK default eventually gets here
FEBC  restore and exit
FEC2  RS232 timing table
FF48  IRQ and BRK start here
FF5B  empty
FF81  jump table for kernel routines
FFFA  NMI vector
FFFC  RESET vector
FFFE  IRQ and BRK vector
