the newer PET machines (not 2001), Atari 8bit, and the Apple ][ (thanks to
Kevin Ruland, who did the port).
C16: Works with unexpanded or memory expanded C16 and C116 machines.
However, a maximum of 32KB from the total memory is used. The Plus/4
target supports up to 64K of memory, but has a small code overhead
because of the banking routines involved. Apart from this additional
overhead, the Plus/4 target and the C16 target are the same. 16K
machines (unexpanded C16) have 12K of memory for C programs available,
machines with 32K or more have 28K available. The actual amount of
memory is auto detected.
C64: The program runs in a memory configuration, where only the kernal ROM
is enabled. The text screen is expected at the usual place ($400), so
50K of memory are available to the program.

The C program runs in bank #0 and has a total of 48K memory available.
This is less than what is available on its bigger brothers (CBM

execution bank (#0) to allow the use of sprites.
