The Neo Geo MVS board purchased recently sadly was not proivided with the service manual, so embarking upon an internet information quest to locate one began, my efforts so far have drawn a blank in locating the specific MV-1FS service manual however my assumption is the manual will be similar to the MV-1F service manual.
To assist all other future consolized Neo Geo MVS builders I have included links below to all the Neo Geo MVS Slot 1 service manuals so far found, these are in PDF format for easy reading and downloading. So if you are looking for circuit diagrams or DIP switch settings enjoy!
Update: I have been informed the MV-1FS is a Spanish variant of the MV-1F where the ‘S’ designates the board was destined for the Spanish arcades.
