34: "Sidney Omarr" should be "Sydney Omarr"
54: "Woolridge" should be "Wooldridge"
It appears as "Woolridge" here, and in numerous other sources (including a historical note on TRW's own website), and as "Wooldridge" on Wikipedia and in some other places. This photograph of a magazine ad from 1958 or '59 establishes that the real name was "Wooldridge" (read the text, not the caption). In addition, the New York Times obituary of the company's co-founder reads "Wooldridge."
84, 133, 196: "didt'n" is repeated several times, so maybe this is Pynchon being colloquial
91: "Thomas Arnould" should be "Arnold"
105: "he can't understood why"
144: "hadt'n" - as with "didt'n," probably an intentional colloquialism
200: "anydody" should be "anybody"
210: "deperate" should be "desperate"
