Programmierbare Elektronische Rechenmaschine München or PERM is a stored program controlled electronic computer Munich, built under the auspices of Hans Piloty and Robert Sauer 1952-1956. Some jokingly called it "Pilotys erstes RechenMonster" (Piloty's first calculating monster.)
The machine is now displayed in the informatics (computer science) exhibition of the Deutsches Museum München.
