BINAC

The BINAC (Binary Automatic Computer ) was a mainframe computer, which was built in 1949 by the Eckert - Mauchly Computer Corporation.

The BINAC was a direct successor of the ENIAC, which was constructed on a binary number system (The ENIAC used a decimal system ). BINAC was by J. Presper Eckert and John Mauchly of Eckert - Mauchly Computer Corporation designed and built for the Northrop Corporation. The computer had two independent processors, CPU, each CPU, each with 512 data word, delay line memory based on mercury. The BINAC used 700 vacuum tubes. The CPU had a duty cycle of approximately 4:35 MHz, which manifested itself in an access time of about 10 microseconds. Programs and data entered via an octal keypad.

Northrop took the computer from BINAC in September 1949 and transported him to their office. Although the BINAC computer passed the acceptance tests that were performed at Eckert - Mauchly, the machine never worked properly at the Northrop Corporation. Probably the machine was damaged during transport.
