HP-41CY re-initialization ROM

[PeterP]

Juergen, that makes total sense for the kick-off of the initialization. My concern was with the pages where you store the OS. My understanding is that you use a CLONIX which has the init module on page 4 and the OS/A on page E and the OS/B on page F.

Assuming this is the case, here is the problem case I was thinking of: Assume you have messed up pages - including junk in polling points - 8, 9, E, F. You can clear of course pages 8 & 9 as they are not masked by a plug-in module (which takes precedence). But how are you clearing the polling points in pages E & F, as they are masked by the CLONIX, aren't they?

Not sure if this question makes sense.

Cheers,
