Building an 8-bit breadboard computer (SAP-1)
While this is not an easy task when you don't have much experience in electronics, fortunately I took courses in my uni that involved digital logic, electronics and boolean algebra so it came in as a good foundation from which I can start building up.
You can buy the 8-bit breadboard computer kit directly from Ben, but it only has exact number of components from which you can build the computer. Which is logical, since it's a kit.
However, I went the other way around, and since I wanted to build my own electronics lab at home, I realized this was the chance to start gearing it up. So in early February, I made a list and ordered most of the components online (Amazon, Ebay, Mouser, and mostly AliExpress).
This page will be updated depending on my progress.
