While you are waiting for the configuration setup, I am giving you some home work to do

This home work will do bank switching between the Finance 16KB ROM and the CurveFit 32KB ROM.

Hi Sylvain,

here is my trial :-) it is running - thank you very much for putting me deeper in this field. Essential is the POKE "2C000","00" when switching the banks, otherwise the calculator hangs. So this is very necessary. (I tested it too).

An open question is, how do I POKE the possible max RAM afterwards, cause of the different ROM sizes with every bank-switch I have to change it? Or should I take the minimum RAM when the maximal ROM (per size) are loaded? How to identify the maximum possible free RAM after bank-switching and does it destroy the mainRAM?

regards
Erwin
