> I write all my code in assembly on paper then manually translate into opcodes

LOL! There was actually a time (way back when dinosaurs still roamed the Earth) when that was actually how it was done. ;)

(I remember as a kid having to look-up hexadecimal 6502 CPU opcodes on a chart then type in a huge list of hex into the computer to write "machine code" if you wanted anything faster and more powerful than BASIC.)
