but has a new entry point at 60111 ($EACF).

60130 ($EAE2) the receive routine has some address changes and is
moved to 60128 ($EAE0).

60177 ($EB11) the serial input ready interrupt service routine is the
same, but the new entry point is 60175 ($EB0F).

60222 ($EB3E) the SIO subroutines have some changes and a new entry
point at 60220 ($EB3C).

60270 ($EB6E) the load buffer subroutine is the same, but moved to
60266 ($EB6A).

60292 to 60905 ($EB84 to $EDE9) all of the routines in this area are the
same, but have entry points four bytes lower in ROM (i.e., 60288;
$EB80).

60906 to 62014 ($EDEA to $F23E) these routines are the same and at
the same locations in both versions.

62015 ($F23F) test for RAM and special cartridge has the same entry
point, but has some changes to the routine.

62038 ($F256) RAM check subroutine has changes and a new entry
point, now at 62036 ($F254).

62081 ($F281) the hardware initialization routines, have changes and a
new entry point at 62071 ($F277) in the new ROMs. The changes
continue to 62159 ($F2CF) where everything again becomes the same
for both versions until the end of ROM at 65535 ($FFFF).
