8 bit computer, ALU complete Everything is connected now on the ALU board. the bus has been connected (blue wires) the A register is connected to the ALU chips (purple wires) the B register is connected to the ALU chips
Switching over to OS High Sierra immediately? Normally I would switch over to a new version of Apple’s Mac OS as soon as it comes out. “It just works”, right? In the case of the upcoming switch to Mac OS
8 bit computer, building up the ALU The ALU Building up the heart of the computer, the two big chips are 74LS181’s (4 bit ALU’s, hence there’s two of them). The two little chips below them are the 74LS245 tri-state
8 bit computer, building the ALU I’m in the process of building the Arithmetic and Logic Unit (ALU) for my 8 bit computer. So far, as you can see, the complete B register and half of the A register are
Replacement soldering station My old faithful soldering iron died… It served me well during numerous years, but finally it gave up. It just does not produce heat anymore. Soldering station So, time to select a new one. I decided
8 bit computer, clock circuit The second print I made is the computer clock:
8 bit computer, program counter and reset I’m busy transitioning my 8 bit computer from the breadboards I built it on to experimental PCB’s. They will be on a bus print. Here’s the first video:
Debounce made visible The problem When using mechanical switches in electronic circuits we encounter the difficulty of what is called “bouncing”. A switch often contains a spring-like contact that, when pushed, bounces up and down sometimes and in doing so,
