Apple 2a
Custom ROM for the Apple 2e. Looks mostly like a real Apple 2e, but
when you type RUN, the code is compiled instead of interpreted.
Runs between 5 and 30 times faster.
Supported features: The classic way to enter programs with
line numbers, 16-bit integer variables, HOME, PRINT, IF/THEN,
FOR/NEXT, GOTO, low-res graphics (GR, PLOT, COLOR=, TEXT),
POKE, and basic arithmetic.
Not supported: Floating point, strings, AND, OR, NOT, negative
integers, high-res graphics, DATA/READ/RESUME, GOSUB/RETURN/POP,
DIM (arrays), REM, keyboard input, and cassette I/O.
