Thank you!

Ding Wen is now starting to look into... 6502 assembly language!

What is the simplest way for him to learn assembly? The fun way?


Pencil, piece of paper, and a guidebook to the instruction set that also
shows the hex opcodes.

Write the assembly on the rightmost columns, then write the machine language
to the left. Just like the Monitor's disassembly screen.

Power on the Apple II, type in the machine language hex bytes in the
Monitor, and go.

For learning, this seems to give two advantages over using an assembler
program:

1.) You're learning the machine language opcodes too
2.) Pencil and paper is just more convenient for shorter programs

I've been using this method recently. Plus it allows for an instant
hard-copy of my program in case of computer disaster!


That's about as "fun" as toggling Altair 8800 switches.  :-)

No, no, no. YOu'll get blisters on the sides of your fingers throwing the toggle switches, I've never gotten a blister from typing (or using a keybpad). Plus, one has to convert to binary to input to the a set of switches, you can use hex with a keyboard.
