Document Summary

70% of u. s market share from the 50"s onwards. Ibm"s goal was to produce the fastest machine possible. (possible first super computer) Us navy"s bureau of ordinance was having trouble finding someone to produce a machine capable of this type of large computation problems. Ibm agreed to develop it, even though it wouldnt make any money. 264 williams tubes : 3600 words x 16 bit words (17th for error checking) Significant because improved the design of magnetic tape drives (x5 speed). Designed at the same time as the norc. Advantage over competitors. (leased at ,000 per month. Successors: first group - 702, second group - 704, 705, replacement for second - 709. After completion of the norc, ibm initiated a research project to determine the feasibility of developing a machine at least 100 times faster. Multiple read/writes in a disk pack over magnetic drum. Pipelining: as one instruction was executed, next 5 would be accessed and partially decoded.
