Hi Erwin,

I'm talking about OTF BS. ROMCOPY can't be used with OTF BS. See the Bank Switching article.

Bank Switching is a feature I proposed to Hans about a year and a half ago. Shortly after that Hans extended the feature to swap banks on-the-fly. After HHC2015 I put together the FRAM71 Toolkit and wrote v1 of the Bank Switching article, but we had no idea of what the "rules" were. Consequently, the safe thing to do was to try to avoid OTF BS. Since then Bob and Sylvain have given clues that appear to define the rules for using OTF BS and those are in v2 of the bank switching article.

So when you say, "no one did bank switching in the forum", I don't know what you mean.

Hi Dave,

sorry my comment was no criticism about the feature bank switching. What I meant in my post is, that there are some FRAM71s out there and the experiences are very small - that was I'm wondering. Maybe its my bad english too. I am grateful for the initiative for the hardware and software - you all did a very good job and helps to have useful possibilities with our ancient calculator. The FRAM Toolkit, the guide from Sylvain and the good description from Hans was a great help for me otherwise it would not be able to make the configuration.
I use the HP71 with small basic-programs in my job and in my study (in my old days) and the HP3421A but not in 'deep' programming- But now with the FRAM71 it could get more practical for me instead of switching out modules and with PIL-BOX and the pyilper its easier for my to handle my files instead with the floppy disc.

I didn't, use ROMCOPY after the first basic installation. My problem is that I was not able to start initiate the other banks with the first POKE like Sylvain proposed. Maybe there is a mistake from me - don't know. So I tried to describe exactly what I did so it could be helpful to go further.
I'm ready to continue further testing - next step is like a wrote in my last reply in order to prevent a fault regarding the LEX files.

best regards
Erwin
