ORACLE (computer)

The ORACLE or ''Oak Ridge Automatic Computer and Logical Engine'', an early computer built by Oak Ridge National Laboratory, was based on the IAS architecture developed by John von Neumann. As with all computers of its era, it was a one of a kind machine that could not exchange programs with other computers (even other IAS machines). It used vacuum tubes, transistors, and diodes. It used a Williams tube for 2048 words of memory. Its addition time was 70 microseconds, the multiplication time was 370-590 microseconds, and the division time was 590 microseconds. These times include the storage access time, which was about 62 microseconds.
The ORACLE pre-dated input from disks and the use of punch cards with computers; it used paper tape for input and breakage of the tape was a frequent problem.
