Computations of the machine are checked at several points for possible errors. During the mathematical operations in the arithmetic section of Mark III, answers are double-checked at every stage in the problem before going on to the next stage. To insure that the final typed results are correct, all numbers are recorded twice on the magnetic tape by two parallel and independent systems. Unless both numbers on the tape are identical, the striking action of the type bars sets off an alarm and stops the typewriters...
...Mark III, which was begun in May, 1946, has been built for the Bureau of the Ordnance of the U. S. Navy to be used at the Naval Proving Ground Command at Dahlgren, Virginia. It is anticipated that testing operations will have been completed by the first of the year and the machine will go to the Navy at that time...
...Mark III, a bakelite and steel instrument, is about 30 feet long and fifteen feet wide and weighs close to ten tons. It contains 100 miles of wire, about 4500 vacuum tubes for the electronic operations, 3000 relays, 2500 magnetic heads and play-backs to carry the information to and from the storage drums, and 400,000 solder connections. A staff of about 40 worked on the development and construction of the machine...
Benjamin L. Moore, assistant director of the Computation Laboratory, and Way Doug Woo, assistant professor of Applied Mathematics, were directly in charge of its development, design, and construction. Mechanical design and construction of the internal high speed magnetic drum storage system, one of the major components of Mark III, was the work of Robert Wilkins, assisted by Dexter Smith...
Charles Richards, who had previously worked on Mark II and will go to Dahigren with Mark III, also worked on design problems throughout the construction period...
