Let’s first look at the 74LS; a quick google search will yield the datasheet on the first hit: We do require a clock for the 74LS Swtpc at English Wikipedia.

As echad said look at the datasheets and have a go at a schematic of a and 74LS connected together.

Have you tried reading the data sheet? So we have some knowledge about that chip; what about the timer? Email Required, but never shown.
A couple pages down and we find a logic table: However, since you are probably not accustomed I admit, I’m not ideal at reading them to going through datasheets, I’ll try to guide you through some logic:. Indeed, we must read more to understand. However, since you are probably not ix I admit, I’m not ideal at reading them to going through datasheets, I’ll try to guide you through some logic: Volume 1 contained a tutorial on how to read and create these symbols.
Well it sure seems as though this chip is pretty useful!
