the FP6000 to International Computers and Tabulators. At I. P. Sharp Associates In December 1964 most employees of Ferranti-Packard's computer group were laid off. Along with six other former FP employees he formed I. P. Sharp Associates. He was vice-president from incorporation to his retirement in 1989. In 1966 he, Larry Breed and Richard Lathwell began work on the APL\360 interpreter. Lastly, APL\360 owes much of its superior time-sharing performance to Roger D. Moore, of I.P. Sharp Associates, Toronto, who was principally responsible for the supervisor. Its design has not been described to the extent it deserves. This team received the Grace Murray Hopper Award from the Association for Computing Machinery (ACM). It was given: "For their work in the design and implementation of APL\360, setting new standards in simplicity, efficiency, reliability and response time for interactive systems." In 1970, Moore became project leader of IPSA's speculative DOS/360 COBOL compiler project. Although the compiler had satisfactory performance, the market did not accept it. IPSA offered APL time-sharing service starting in 1969. By 1975, the inflexibility and communication error intolerance of time-division multiplexing were no longer tolerable. He became the chief architect of the IPSANET packet switching computer network. In 1976 this system was deployed in North America and London. In 1984, IPSA released Sharp APL for the IBM PC. This package included a 370 emulator written by Moore. Retirement After retiring from IPSA in early 1989, he became interested in opera and chamber music. Along with attending many performances, he has supported concerts, commissions and advanced music education. Compositions funded Moore has funded the composing of many works.
