Critical Evaluation
This oral history interview provides a valuable first-hand account of the design of the Intel 8087 math coprocessor, a significant milestone in computing history. The value lies in the detailed technical narrative from a key engineer, Rafi Nave, who led the design team. He explains complex topics such as the need for a fast shifter, the patent for doubling ROM density, and the rigorous verification of transcendental functions, offering insights not typically found in textbooks. The argumentation is coherent and credible, as Nave’s story aligns with known historical facts about the 8087 and Intel’s operations in Israel. However, as an oral history, it is inherently subjective, relying on memory and personal perspective. The transcript has been edited by the interviewee, which may introduce bias or omissions. The technical depth is moderate; while it explains concepts, it does not delve into the mathematical details of the algorithms, which might be a limitation for experts. The sources are limited to the Computer History Museum’s catalog entry, but the interview itself is a primary source. The title accurately reflects the content, and the interview is well-structured, covering personal background, technical challenges, and the broader impact. Overall, it is a reliable and informative account, though it should be complemented with other sources for a fully objective view.
