I just found a notebook containing listings of assembly code. Much of it is written by hand in pencil and I am not sure why. My first thought was that I might have been working on the code during a school classes. But, the code includes the op-codes and I can’t image why or how I would have looked them up while writing the assembly code. Maybe my printer wasn’t working. But, why would it be so important to write down the code when I would have had it saved on cassette or disk?
It is possible that the code was written back when my Model I only had 4K of memory. Back then I couldn’t run the Editor Assembler program and had to hand assemble the code and enter it into the computer as hexadecimal numbers using a monitor program.
Three of the handwritten pages are a “Explosion” subroutine. It may have been written for a game I called “Raid” which was a simple first-person shooter where the player panned around in space shooting bugs which, when hit, splattered on the screen.
