BARK (Binär Automatisk ReläKalkylator) was completed in February 1950 at a cost of 400.000 Swedish kronor. BARK was a 32 bit machine and could complete an addition in 150 ms and a multiplication in 250 ms. It had a memory with 50 registers and 100 constants. It was later expanded to the double memory. BARK was built using standard phone relays .

The machine was built with 8000 relays, 80 km of cable and with 175000 soldering points. It was operational on April 28 1950 and was taken offline on September 22 1954.

The engineers on the theam led by Conny Palm was Harry Freese , Gösta Neovius , Olle Karlqvist, Carl-Erik Fröberg , G. Kellberg , Björn Lind , Arne Lindberger , P. Petersson and M. Wallmark

Howard Aiken stated in reference to BARK "This is the first computer I have seen outside Harvard that actually works.".

BARK was developed by Matematikmaskinnämnen at the same time as BESK.
