I have a NEO-MVH MV4FT 4 slot PCB for sale. I have not had it running for years and at this point I have no way to test it. The last time I tried it all 4 slots worked, but I could not get it to cycle through the slots with the select button. More than likely the problem was in the select button wiring, but I never took the time to sort it all out.
