The easiest way would be to enter the monitor (CALL -151) and read out
the values from the memory address ($C100:$FFFF).
FYI: $C100 ~ $C7FF is for ROM assigned to each peripheral cards
$C800 ~ $CFFF is the switchable ROM available for each
peripheral cards
$D000 ~ $D7FF "D0" empty ROM socket
$D800 ~ $DFFF "D8" empty ROM socket
$E000 ~ $F7FF Integer Basic ROM
$F800 ~ $FFFF Monitor ROM
