HP-12c 'comma' variant (?brazil)

Wow.

So in the end these are official HP-12c units.

Gene, do you know the backstory with the firmware?

I wouldn't use the term 'bug' for this. This is a variant.

A bug implies this is an error or fault introduced to otherwise regular HP-12c firmware. I suspect this firmware may use none of the code from the regular HP-12c.

come from?

This is the key question! Who wrote it? Why did they write it given the regular firmware is available to both HP and the public? How did it get past testing?

Why?!

The biggest issue is that there are now HP-12c units in circulation that break the 'de-facto' standard in financial TVM calculations.
