Use your multimeter and the JAMMA pinouts (most versions of Silver Strike Bowling use a JAMMA I/O board but you might check your manual to make sure this is the case for yours) to make sure that the correct voltage is. For me this is the best and easiest I/O board to use. Apparently I can fry the thing if I just use it directly since the voltage is too high. MVS is arcade hardware, they're made for pure RGB and Comp Sync straight to the monitor PCB. The adapter basically just does that repinning for you. I've been using my CMVS on my old TV directly through RGB scart, and it worked perfectly, however after getting a new TV that doesn't have scart inputs, I thought getting an OSSC would do the trick. #2.
