Test PC mining (museum)
Do you want to see what mining was like in 2011 and 2012? Here is the old Bitminter client, a java app for mining bitcoin with a PC. You earn nothing mining bitcoin with a PC! For actual mining you have to buy a modern bitcoin ASIC miner. This is only for nostalgic museum purposes.
Java must be installed first.
The client can be removed from your computer by clearing the Java cache.
