@Setok@attractive.space GEOS for the C64 and Apple II was a GUI for 1 MHz 6502 machines back in the day – without slop coding... Apple's IIgs had an even more advanced GUI using a 65816 CPU running at 2.8 MHz.

@me_@sueden.social @saruwine@mementomori.social ah yes I had forgotten about GEOS, which is sweet. Did it support overlapping windows? Also the C64 at least had hardware sprites which could be very useful for a rudimentary GUI (though I’m not sure if GEOS used them).
