This is a computer composed of 74 series digital circuit chips, which meets the five basic components of computers proposed by von Neumann, including arithmetic unit, memory, input device, output device and controller. Its core is a 4-bit CPU composed of 10 74 chips, including ALU (arithmetic logic unit), ID (instruction decoder), MUX (data selector), PC (program counter), and registers A, B and output registers.
The ROM (read-only memory) connected to the CPU is used to store programs. It can be programmed by dip switches and can use 12 instructions, and can write up to 16 instruction programs.
This product is divided into kits, SMD soldered and finished products (all soldered + tested). Since SMD soldering requires hand soldering, it takes a lot of time and energy, so the price is relatively high.
If you solder it yourself, you need a certain amount of circuit knowledge and soldering technology foundation as well as enough patience. The schematic diagram, PCB diagram and BOM table are provided by default, and there is no redundancy in the plug-in components.
If you want to solder neatly, it takes about 3 to 5 hours for those who are skilled in soldering SMD components, and it may take a whole day for those with little experience. I hope you have enough understanding of the workload to avoid losing patience and giving up halfway.
