mos tap

Solid state circuits are increasingly intruding into fields that were once the domain of electromechanical components, but only recently has it become possible economically to replace the simple electromechanical switch by an electronic system with no moving parts - the Touch Activated Programmer (TAP). In last month`s issue a TAP was described which utilised TTL IC`s. This month we publish a new design based on COSMOS logic packages.
