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`,
|
|
|
|
|

|
