RE: Early (earliest?) HP-41C find.
Hi all,

I've managed to extract the .ROM images from pages #0, #1 & #2. (Ver. D, D, D)

You can use V41 emulator (release 7B) available elsewhere to test and play with them.

Please PM me with your e-mail if you're interested in these .ROM files.

Since earliest 41C OS release was D, D, E; main interest will be in comparing "D" ROM2 with its "E" counterpart, and see what changes HP made in its first production batch.

Obviously, M-code expertise (which I don't have) will be required for this task. Therefore M-coders help will be much appreciated in documenting these changes.

Best wishes.

Diego.
