10 or 11, Sinclair ZX Spectrum, BASIC. most likly i started by typing in the examples from the book, working from there. changing lines of code, see what it does to the program. some two years later i got a c64. the basic was a lot worse, but it was the machine i got around my head to assembler, or at least machine code - because i did'nt understand the concept of the assembler, but i very well understood the machine-code-monitor in the final cartridge. but rasterbars, and softscrollers with (stolen) musik and sprites on the bottom/top border, was as far as i ever got.
