Ok this doesn't seem to be the correct forum for this kind of question but the Intel support directed me here. If anybody know where I should turn, please let me know.

I got an Intel 87C196CAmcu which runs just fine. Now I have to transfer the code to an Intel 87C196CB mcu but I can't get it to work. Both mcu uses external flash and ram with a fixed 8-bit system and runs the code from the flash (no internal code).

I got some questions about the differencies in mcu layout and memory mapping that I need some help with.
