I vaguely remember Bob suggesting something about LEX files and poll handlers in the swapped F-Blocks. Has this been verified? I don't recall Hans saying anything about limitations with F-Blocks that contain LEX files. There are other cautions that should be observed when using OTF BS. See the FRAM71 Bank Switching, v2 article.

I don't think in the case it's about the LEX-Files. I did the installation like Sylvain's guide and only let the ROMCOPY in the IRAM. If this is real not possible - that would mean that no LEX files in the banks - then the bank switching function would be useless - I think it's another problem but I have no more idea. The only thing I could try would Bussi Erwin to cancel all programs on the calculator that this part could be excluded. If there are no other opinions I will give it a try tomorrow :-) Meanwhile I'm used to quickly set up the calculator again ...

The problem comes with the first POKE command from Sylvain's very detailed proposal (thanks on this point). Maybe there is the problem - it's not clear for me if the deactivate and activate process described in the bank switching article (http://www.hpmuseum.org/forum/thread-697...RAM71+Bank) is on the first POKE necessary and when how to do this properly?

I'm wondering that no one did bank switching in the forum, although there are some FRAM71 out in the wild :-)
