Introducing a fierce man who created an 8-bit computer that actually works in the factory building game 'Factorio'

'Factorio ' is a real-time simulation game that aims to escape from the planet by building a factory line on the drifting planet and automating various tasks. With Factorio, a fierce man who has created an 8-bit computer that actually works has appeared.

Factorio created an 8-bit computer by sorek , a user of the image-sharing service imgur . In the movie below, you can see how the 8-bit computer created by sorek is running a program to find the Fibonacci number.

In the 8-bit computer created by Mr. sorek, ' clock (CLK)' ' program counter (PC)' 'bus (BUS)' ' ALU ' ' register (A and B)' ' address decoder (RAD)' 'memory ( Elements necessary for a computer such as 'RAM)', ' instruction register (IR)', and 'display (LCD)' are reproduced, and it is possible to operate at 2Hz.

8-bit computers are made exclusively from the equipment that appears in Factorio's games. For example, in a display that displays the calculation result, the calculation result is output by inputting a number from 0 to 9 in the

'constant circuit ' and turning on the appropriate ' lamp ' via the 'conditional circuit'. I will.

The memory is also created by arranging a large number of conditional circuits. On the 8-bit computer created by sorek, any program can be executed by

manually recording the machine language in this memory.

In addition, Mr. sorek tried to create an 8-bit computer with Factorio by referring to the movie series that explains how to make an 8-bit computer including the following movie.
