BARK was an early electromechanical computer.
BARK was built using standard telephone relays, implementing a 32-bit binary machine.
It could perform addition in 150 ms and multiplication in 250 ms.
It had a memory with 50 registers and 100 constants.
It was later expanded to double the memory.
Howard Aiken stated in reference to BARK “This is the first computer I have seen outside Harvard that actually works.”
