minus-squaremrkitelinkfedilinkEnglisharrow-up2·1 year agoOne of my oldest programming books is all about using machine language to program. https://vintageapple.org/apple_ii/pdf/Apple_Machine_Language_1981_(raw-bw).pdf At the time, even assemblers cost money. I remember saving up for Merlin which is an assembler for the Apple II.
minus-squarejormaiglinkfedilinkEnglisharrow-up1·1 year agoWhat does he mean by machine code? Like assembly files or literally 1s and 0s?
