Properties of a Pocket Calculator for Astronauts

There is another archived post entitled "HP-41 in Space - Shuttle Training Manual" and posted by Bill (Smithville, NJ) on 24 Apr 2007 in the HP Forum Archive 17. He obtained a copy of the "Hewlett-Packard 41 Calculator/Shuttle Portable Onboard Computer Training Manual", which was a 45 page manual dated November 1985. The manual covers both the HP-41 and the Grid Computer. He said a lot of it covers pretty basic HP-41 operating procedures.

He noted that the manual included a brief description of six Space Shuttle programs:
Center of Gravity
Orbit
Alarm/Hex
Landing
Proximity Operations
Tail

And, he said "Now for the real teaser - They refer you to the 'HP-41 Flight Procedures Handbook' for details on each program." He was unable to find this second manual.

That second manual is listed on the August 1988 Johnson Space Center Document Index as document number 18778, entitled HP-41 COMPUTER FLIGHT PROCEDURES HANDBOOK, dated 12-07-84, by D. A. Lamar. Unfortunately, I cannot find this document on the NASA Technical Report Server.
