HP-41: OS4 module and Ladybug 1A

[Artur - Brasil]

This is a fabulous work! Congratulations!
Now, those ones that are afortunate to have one NovRam or other special RAM/ROM modules will have two great calculators in one! What a precious work!!!

I, in my 54 years old, can't understand very well the 41 internals and assembly language.
Maybe an online master class from you, experts, could make us - people like me in a need of some assistance - star in this new world!!!

A summer (or winther) online course?

Again,
Congrats and thanks a lot!
