your engine30-1241-0 would need ps 3 steam kit installed and then you would have full DCS and sounds etc just like your 2-8-0 engine did! some tech's might be able to install board in engine but ii is a tight fit in engine! if board can be put in engine would cost less ! asc tech can install kits around $250.00 to $300.00 depends what techs you ask price varies !
