I wrote a WIMP based gui on a ZX81 with 1Kb RAM, drop down menus used XORing, used keys to move cursor as no mouse back then, trouble was to make it useful for programs had to increase ram much higher like 16Kb, I used machine code and especially for low level graphics code, was fun to do 🤣
Damn, how low can one even go?
640K of memory should be enough for anybody.
Linux system requirements:
Electricity (optional)
4KB got us on the moon.
I had a GUI on a computer with 256kB RAM on no hdd.
