HP-41 Manuals and Quick Reference Card Revisions

[vervalin]

Thanks Bob, Nice to be chatting with you again after our lengthy discussion on the PPC ROM last Fall. BTW, you purchased the Synthetic Programming Quick Reference card I sold on ebay at the end of 2022 :-) Hope you are enjoying it!!

Good information in your response.. Thanks..

For example though: Card Reader Quick Reference: Rev B, 11/79 and Rev C, 3/82
Are identical. I have spent WAY too much time comparing them - LOL. If there is a difference, then it is invisible (other than the actual Rev indicator).

Anyway, there are almost certainly differences in the more lengthy manuals but those differences would be hard to find I think. These Quick Reference cards are pretty easy to compare.

Thanks for the quick response!!

Regards,
Paul
