• In 1978 he joined the IBM 801 project in the Computer Science Department of the Thomas J . Watson Research Center in Yorktown Heights, New York, and moved to the Mathematics Department in 1984.
• In the mid-1980s to early 1990s, a crop of new high-performance reduced instruction set computer ( RISC ) microprocessors appeared, influenced by discrete RISC-like CPU designs such as the IBM 801 and others.
• Perhaps the project where his innovations were most noted was in the IBM 801 minicomputer, where his realization that matching the design of the architecture's instruction set to the relatively simple instructions actually emitted by compilers could allow high performance at a low cost.
• Although the company knew that it could not avoid competition from third-party software on proprietary hardware Digital Research released CP / M-86 for the IBM Displaywriter, for example it considered using the IBM 801 RISC processor and its operating system, developed at the Thomas J . Watson Research Center in Yorktown Heights, New York.
