I did it for Bon Voyage. After I learned the machine I went through the manual, redid it, and fixed the errors. There were several. I did them in red so it would be possible to track the updates.
I also redrew the playfield diagram from the Bally parts manual and made it all vector. Then made new charts for rubbers, lamps etc. Also made a custom rules sheet as that did not exist. All those docs are on this web page:

I also scanned and cleaned up the schematic, including fixing a few errors it had.
Later, I did a complete vector redraw of an EM schematic, but that’s another whole topic (Monte Carlo).
