Hello
I am an HP-41 owner since 1977, and in early 80s I wrote the program for monitoring PT6A aircraft engines and I sent to the HP Users Library, and they published as:
02011-41 Engine Trend Monitoring Program for PT6A-11/21/25/27/28.
I found the detail I enclosed in the HP Users Library Catalog 1989.
Since that time I loose all paperwork for that program, and I would like to know if somebody could have that program I wrote.
Greetings
Fernando Mujica
