I did not order the beta machine because I was afraid it will distract me too much of the clupdate project but I which I did. Sad

Not hard unless you haven't picked it up for awhile, hence the dead batteries. Thank you flash ram!
Same thing for me, for the same reason as above, I have not really used my 71B's since May 2016.

No you don't! Wink

Restoring the calc from 0C9>800.
Of course all the memory locations have changed for free memory or have they?
It has been quite a while that user free Flash space has been used for the ROM modules. Lucky for you, there are lots of free Flash space on the v5, at least for now.

Now you are being too hard on yourself, but I must agree that there was a book that was supposed to be published ... LOL

And there is an encyclopedic knowledge base required, plus I don't have a pocket version of Sylvain or Bob :-)
Ouf! Lucky me!

I booted the calc with my disc drive and card reader to fill it with routines.
I would like to save this state in flash RAM before I start to explore version 5 fully.
Is there a new memory type, Flash RAM, in the 41CL ? (just teasing)
Flash address range 0x219 to 0x3FF are currently free and could be used for your backup.
IMHO, using 0x380 to 0x3FF should leave you enough space for your usage and at the same time leave enough space to not collide with upcoming ROMs.

Kind regards,
