Another bug hidden for over 40 years ... ?

However, because it is probably easily missed, I have added it as a separate download here (plus now it should come up more easily on searches for the part number):

In the same way, there is an addendum for the Extended Function/Memory module 1B (for the CV).
Probably many of us are using physical or emulated 41CX with embedded XF-2D for which the addendum is no more relevant,
but my CV has still a XF-1B module in it, and it seems the corrected version 1C is somehow rare - even a powerful user/collector doesn't have it

The addendum is available on the hp41 archive site.
The most notable and annoying bug is :
"After a file in extended memory is purged, there is no working file.
[...] you should always define a working file before executing functions that operate on it;
otherwise, all files in extended memory will be lost".
