Ok thank you for the advice, I will post on both of those
Two more questions here (in case someone knows, I will also post on the other forums), is there a good place to buy another "Astra IO-3 board", and can I just take the ROM chip out of my board and put it into the new board (or am I over simplifying it).
Also if I replace the battery for a battery holder and a watch battery will any of the chips lose their code (is there a battery backed RAM chip - the security one)?
