High-level verdict on Post 29

Net assessment: The post is mostly accurate on its core narrative (CDC 1604 specs, delivery to NPS Monterey January 1960, Cray as architect, ERA→Sperry→CDC genealogy, FNWF/FNMOC continuity, NCAR-CDC 3600 myth correctly debunked). The Cray bio is largely correct (Battle of the Bulge confirmed, BSEE/MS Minnesota confirmed, Sept 28 1925 birth confirmed, Oct 5 1996 death confirmed). The Norris bio is mostly correct (born Nebraska, ERA 1946, CDC 1957, died 2006). The Mullaney bio appears correct based on available sources.

Major errors that must be fixed before publication:

  1. CDC-IBM 1973 settlement was ~$80M, not $600M (Coda section — order-of-magnitude error)
  2. CDC 1604 announcement venue: NOT WJCC 1959 Los Angeles — WJCC 1959 was San Francisco in March; CDC 1604 announced Oct 16 1959 most likely via press release
  3. Cray’s father: civil engineer, not “city engineer” (per Wikipedia)
  4. FNWF named in 1961, not 1959 — naming history elision
  5. Cray-3 (Graywolf) was a CCC product, one unit delivered to NCAR, not “cancelled” (the post conflates Cray Research with Cray Computer Corporation)

Minor errors / imprecisions:

  1. “Westinghouse-trained” for Norris is misleading; he was University of Nebraska 1932
  2. “$300,000” Cray Research seed money is disputed; Wikipedia says $250,000
  3. “first fully transistorised scientific computer” overstated; “first commercially successful transistor scientific computer” more accurate
  4. BESM-6 “CDC compatibility” claim is unverified in Wikipedia BESM-6
  5. Cray accident: Sept 22 1996 (Sunday), not “22 or 23”
  6. IBM 709 “contemporary” with 1604 is muddled — 7090 was contemporary (and transistor)
