Скачать или смотреть Input Magazine Issue1 MachineCode UDG : Tank

Input Magazine was a publication in the early 1980's which aimed to teach programming and had lots of type in programs for all the UK Microcomputers of the era - not least the ZX Spectrum.
The first bit of code is a frame print routine that you type in then run, and it stores the machine code in memory for later use. This prints a "large" 3x3 UDG (User Defined Graphic), and being machine code is fairly fast. The next bit of code (in green!) is the code to load a tank graphic into the UDG and move it left right, and also pressing space fires the gun. Links:
