Building 8-bit computer in VCB simulator (WIP)

Below you will find schematics and short explanations on how to build 8-bit computer starting from logic gates in Virtual Circuit Board (VCB) emulator.

Prerequisites:

• Basic knowledge of logic gates (AND, OR, NAND, …)
• Familiarity with drawing basic schemes in VCB

By implementing computer from scratch you’ll learn:

• Logic gates
• Components (ALU, Registers, Memory, Display)
• CPU Architecture
• Assembly
