Polish developer wrote software Bitcoin miner for Commodore 64 - computer 1982 Year of release. He essentially rewrote the code for the Game Boy mining program. 1989 of the year.
Maciej Vitkowiak (Maciej Witkowiak) posted the code on GitHub, which allows you to mine BTC on Commodore 64, one of first mass market computers, with a productivity of 0.2 h / s. Commodore 64 was released in 1982 year and became the first widely used 8-bit personal computer, game-oriented and music-making. The home computer had 64 kibibyte of RAM, whereas modern computers usually have from 4 to 32 gigabyte of RAM.
Mining can be implemented on almost any computer - it comes down to processing hash functions. In the early years of Bitcoin's existence, it was possible to mine on a home computer., now, for a month's earnings above the average salary, the purchase of equipment for tens of thousands of dollars is required, and the full payback period is measured in months, and often for years.

Commodore mining code developer 64 Maciej Vitkowiak, estimated the hash rate on an old computer at 0.2 x / s. For comparison, modern ASIC miner, eg, Antminer T19, counts hashes at a rate 84 Th / s. Therefore, it is unlikely, what's on the Commodore 64 it will ever be possible to mine a block of Bitcoin or other common cryptocurrency.
Since on any computer you can run the process of BTC production, developers have recently begun experimenting with a variety of old hardware. Last month, a YouTube user turned
Game Boy 1989 of the year – Nintendo's first major handheld video game console – In the miner BTC. Code for Commodore 64 на Github – branching code for the Game Boy.
Vitkovyak noted, that Commodore 64 does not handle 32-bit computations very efficiently, which are needed when executing hash functions. He gave users a recommendation: "Just enjoy this experience".
Recall, that at the beginning of the year the miner from the United States installed
a mining farm from Nvidia graphics cards into the trunk of his BMW i8 and powered it from the car's electrical power system.
