Homebrew: 8-bit Computer Clock

2017-05-15T15:29:50Z

MichaelWagner:

== '''Clock Module''' ==

The clock module produces clock pulses, these pulses synchronize actions. If the computer is like an orchestra or marching band the Conductor would be analogous to the clock, it dictates the speed at which instructions are carried out. In our case we have a specialized clock that allows for variable speed and manual clock pulses also. Also the clock demonstrates most of the modes used by a 555 timer IC, Bistable, Monostable, and Astable. The clock also uses 3 74xx series chips to control and select the output specifically a 74LS04 Hex inverter, a 74LS08 Quad 2-input AND Gate, and a 74LS32 Quad 2-input OR gate. There are also several other supporting components, including resisters capacitors switches and LEDs.
