Video Description: A simple 4-bit computer is built on breadboards using individual transistors. This computer is called the GSN477. This is because it was built for the Global Science Network, is 4-bit, and contains two 7-stage counters. Sections of the computer are the clock, program counter, ring counter, 10 bytes of memory, opcode register, opcode decoder, control matrix, data bus, accumulator register, output register, register B, and ALU. Circuits are built using NAND digital logic gates, XOR gates, AND gates, inverters, buffers, and tri-state buffers. Larger circuits include D flip Flops, MS D flip flops, Edge triggered JK flip flops, and MS JK flip flops. The computer shows how computers add and subtract numbers while running a simple program and this video was submitted for the #some3 competition. 0:00 Intro. 0:51 Computer overview. 1:30 Example program. 4:12 The clock 4:22 Ring Counter 4:53 Program Counter 5:33 10 Bytes of Memory 7:01 Opcode Register 7:11 Opcode Decoder 8:19 Control Matrix 9:06 Data Bus 9:44 Accumulator Register 10:21 B Register 10:51 ALU 11:15 Output Register 11:35 Building Suggestions References: Walker, J.
