"While it is possible to write programs directly in numerical machine code, it is tedious and error prone to manage individual bits and calculate numerical addresses and constants manually. It is thus rarely done today, except for situations that require extreme optimization or debugging." - (Wikipedia) You tell me? I've been there :) Having 1k altogether gives you no other option ... and had been hooked on forever :) -- ZX 81 1k: Basic, Z80 Machine code -- ZX Spectrum 48k (extended to 80k) w Microdrive: Basic, Z80A Machine code, Assembly -- Commodore 64: Basic -- Psion Series 3a: SIBO -- Psion netBook: EPOC OPL -- Samsung Series 7 (Ubuntu Linux): Java, C++, Javascript -- Raspberry Pi (Raspbian): Python, Java, Scratch :) -- Arduino Uno: Processing3 -- PebbleTime: C, Javascript -- 386DX40 to SurfacePro3 (MS Windows): Java, Python, C, Javascript, Haskell
