Monopoly Triple three player rom help

Its for Monopoly Triple three player the one where the top box has three jp's the standard monopoly man/ community chest and chance jp's

Been looking for these for some time and loaded them into a previous golden game layout, i have the roms running (sort of) but there's a few things i can't suss out

first the volume how do we turn it up on these including top box do i need to add a button or three

the base units run in door open but come up with error 60 and alarm on start up

the seven segs on all four units 3 plus top box aren.t correct 

here's the roms in said layout(s) if someone can sort the above out please.

also here's some roms for the monopoly casino three player set1 if anybody wants to get them running also, i think those are the ones with the notes for a fiver etc
