To utilize 6502 machine code in the Apple IIe monitor, follow these steps:

  1. Turn on the Apple IIe and enter the monitor by pressing the RESET button followed by CTRL+OPEN APPLE+RESET.

  2. Type in the address where you want to load the machine code. For example, if you want to load it at address $4000, type "4000" followed by RETURN.

  3. Enter the machine code by typing it in hexadecimal format. For example, if your machine code is "A9 01 8D 00 D4 60", type "A9 01 8D 00 D4 60" followed by RETURN.

  4. Verify that the machine code loaded correctly by entering the address where you loaded it followed by a period. For example, if you loaded the code at address $4000, type "4000." followed by RETURN. This should display the machine code you entered.

  5. Execute the code by entering the address where it was loaded followed by a space and the letter "G". For example, if you loaded the code at address $4000, type "4000 G" followed by RETURN.

Your machine code should now be executing. You can monitor its progress by entering the address where it was loaded followed by a period at any time. When finished, you can reset the computer and start again with a new program.
