The PS32 board from the steam kit "should" have the correct chain files loaded for steam. In that case, you use PS/2 3V files to load your sound file.

There is no business deal per se other than MTH has not done upgrades as they don't want to compete with their trained techs who do upgrades. If they had no PS1 boards, fixing your locomotive with PS3 boards would arguably be a repair, but if the PS1 board are available then changing to PS3 boards is clearly an upgrade.
I suspect that MTH doesn't do upgrades simply because they had their plate full with repairs, etc. I'm personally not worried about them taking business away, I can't do the work that is already knocking at the door!
