Thanks for link - I had run across it some time ago but a re-read brought up several interesting points.
Each program was "Mission" specific and was on Modules with spare modules being carried. Of course, this begs the question - User Step Code or Machine code? Used on total of nine missions, so there may be nine different mission specific modules.
I'll be visiting Washington this spring, so I'll have to check the HP-41 that is on exhibit at the Air & Space Museum. Worder if they are storing it with or without batteries and does it contain the actual modules that were used for the Sally Ride mission. Thinking of batteries, did they use standard off-the-shelf batteries or special batteries for the space environment. Too many questions - few answers :)
No let's see .... if I carry a set of batteries.. and no one is looking ... Nah - I'd never get away with it :)
What has happened to the other calculators and modules?
I had to laugh at the following statement:
"Because of their low cost, NASA was able to buy several calculators and provide them to members of the crew for their personal use."
With the millions being spent, NASA could afford to buy hundreds or thousands instead of just "several".
I have a friend that's involved in designing satilites and maybe he has some contacts that could help me track down some additional info.
