The BASIC ROM routine to convert integers to floating point is, as Fred
Bowen says, alive and well.  It is the routine to convert floating point to
integers (jump table address $AF00) that does not return it's result in A,Y.
Additionally, *as I said before*, that routine does not work correctly unless
the FAC has had any fractional part removed by INT first.  I don't know if
either of these has been changed by the upgrade ROM, but my fix makes it work
on any 128 (in theory!).  It is simply not sufficient to fix the A,Y register
problem, you also have to do the INT fix.
