Rare findings season is opened!

The intro in the book says that the 41 programs were 'adapted' from HP-67/97 programs, which explains the, um... non-optimal programming/label choices and operational procedures. Although now 41 programs, they are still operated the old way. Instead of "Load the cards" and then use A-E keys for program operation" they simply run the program name in lieu of "Load the cards".

I think this supports Diego's theory; it looks like they made minimal changes to the 67 programs to run on the 41, then likely had them burned in the OTP modules as an expedient. Had they taken the time to re-write the programs to leverage 41 features, they surely could have included several to many more of the original programs. If they had contracted CMT to port the programs, they surely would have made changes to global labels, etc.

Thanks for reporting this Diego, very interesting.
