Three Microsoft Excel calibration programs for the laboratory

HP41-C programs

I started learning programming on a HP-9715 desktop calculator at my laboratory in the end of the 1970's.
When the HP41C handheld calculator arrived on the market the same programming RPN-language was used and programming continued at home.
I made several programs and send them to the HP "Users' program library Europe" so they could be used by everyone.
Unfortunately this library is lost. I retained a copy of most of my listings.
These have been
scanned and they are available for reference.

If time comes I may add more. More in The museum of HP calculators
