 > At the yearly cleanig of the garage found an old box which was used at
 the office for accounting purposes, decided to blow the dust away and give
 it a use... Found out it won't work with Tor Browser, becasue of the CPU.

 either staying idle (in order to keep socksport open for other torified
 applications).
