And of course if you boot the DOS 3.3 System Master on a 64K Apple ][, it
will load the Integer BASIC ROM image (containing the Programmer's Aid
ROM) into the upper 16K of memory.
Then you can switch into Integer BASIC from Applesoft BASIC by typing
'INT' (which is a DOS command). To get back to Applesoft type 'FP' (for
Floating Point, as in floating point BASIC).
INT basically bank-switches in the ROM image in RAM. You can also press
RESET to get back to Applesoft. Switching using either command will init
your environment from scratch (i.e. any BASIC program in memory, either
Applesoft or Integer, is lost).
