How to Build a Computer on Breadboards Using Transistors
How to build a 4-bit computer using individual transistors will be demonstrated and discussed in detail. Parts of the computer include the clock, memory, accumulator register, register B, ALU, and output register.
An example program will be run where load A, add, subtract, output and halt are executed. The computer will be put in a loop where it will continuously add by two and then subtract by two.
Understanding how to build a computer at the transistor level is important information that everyone should understand. Please share this video!
