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), DIM (single-dimensional arrays), POKE, and integer and boolean arithmetic.

Not supported: Floating point, strings, high-res graphics, DATA/READ/RESUME, GOSUB/RETURN/POP, REM, multi-dimensional arrays, keyboard input, exponentiation (A^B), and cassette I/O.
