Oh you know, just brushing up on my British Standard logic symbols. (I’ve never seen these before).

&10;The good author's guide to explaining projects&10;IF YOU WISH to submit articles to sinclair Projects we would appreciate it if you adhere to the following rules.&10;Although they are not exclusive it would help us to evaluate projects if there is some element of compatibility between different pre-sentations.&10;&10;• All manuscripts should be typed with double-line spacing.&10;• Logic symbols should follow British Standards.&10;• Circuit symbols should follow&10;British Standards.&10;• Circuit diagrams should have the values of the components shown, not a reference to a component table.&10;• Parts of integrated circuits should be designated&10;in this way&10;1/4 74LS14, not ICSa for example.&10;• All circuits should be designed for construction using standard Vero-board. Any printed circuit board designs are likely to be returned for conversion. Submission of a project based on a PCB will not exclude future publication.&10;• Any constructional detail which is unusual or slightly complicated should be illustrated with simple hand-drawn diagrams, showing how it can be implemented.&10;&10;For those who are unfamiliar with British Standards logic symbols, they are shown here. The reason for using BS symbols is simple, although controversial; they are used extensively in the British educational system and in British industry. As most of our readership is in those areas we use circuit symbols which are most familiar.&10;&10;U.S.:&10;AND&10;NAND&10;OR&10;NOR&10;NOT&10;EXCLUSIVE OR&10;&10;BRITISH STANDARD:&10;AND&10;NAND&10;OR&10;NOR&10;NOT&10;EXCLUSIVE OR&10;&10;SINCLAIR PROJECTS June/ July 1983&10;June/July 1983&10;An independent magazine published by ECC Publications&10;SINCLAIR PROJECTS&10;&10;&10;THE MAGAZINE FOR THE SERIOUS SINCLAIR USER&10;&10;&10;SIX GREAT PROJECTS&10;CENTRAL HEATING PART II&10;GRAPH PLOTTER&10;DECODER PART II&10;SOUND GENERATOR&10;JOYSTICK FIRE BUTTON&10;SAVE AND LOAD&10;
