Initially the memory for the ROM's will be type 1, IRAM, so that the ROM images can be copied to the port. Then the config string should be POKE'd with the appropriate value to convert the port to ROM, type 2.

Hi Dave, of course you are right - I changed the identifier with the poke. But with my experiments my calculator is in a stage where I can not config it anymore. I get an "ERR:" message when I want to make a new configuration.
No better result with POKE 2C000 with 32 "0". I put the CN2-2 to clear all IRAM but with no better result. I think there are some wrong bits in the memory from my testing where the reset doesn't clear them.
I think I need to clear the FRAM complete. There was an info about this in the forum how to do this but can't find it.

best regards
Erwin
