This build will consist of a breadboard, Z80 processor, 8K ROM, 56K RAM, and a display hooked up via VGA. The computer will run Microsoft BASIC. The goal of this project is to get a better understanding of how different parts of computers are connected, get experience with hardware and software work, and create a controller for the robotic arm. The breadboard is essentially the mother board; thus, all of the chips will be attached in their respective places. The computer's memory will only exist as RAM (Random Access Memory) and thus will not be active once the computer is shut off. The OS (Operating System) is stored on the ROM (Read-Only Memory). This allows for the memory chip to be read even after the power has gone out; however, you cannot edit the information on the chip. In other words, it is a read-only chip. Overall, this build will work as a basic computer to control the robot and for the purpose of experimentation.
