My first ‘computer’ in 1977, was the SC/MP Microprocessor Introkitfrom National Semiconductor (UK) Ltd., which introduced me to the delights of machine-code programming. By 1979, 1 and many others had access to the Commodore PET and Apple microcomputers and we were able to apply machine-code programming to fast data capture and animation, producing, for example, simulations of wave and molecular motion. This experience was soon followed by the AIM microcomputer, which had advanced (sic!) refinements such as cassette-tape storage, paper printout, and Assembly Language. Many of us saw machine-code programming as the advent of a new era inelectronics.
