The top part of the jumptable is mostly the same, but I don't think
SETNAM and SETLFS are in that part. There are also other differences
that are quite annoying (meaning: they corrected some earlier design
mistakes in the VIC kernel). For instance, LOAD and SAVE are meant
to be called from BASIC. The first thing they do is use BASIC routines
to fetch the file name and device number. To use them from ML you must
either set up CHRGET correctly or jump directly into ROM (where exactly
differs with each ROM version :-( ). OPEN however should be usable.
