I am new to this owning a real slot machine as I just purchased this bad boy at a local pawn shop. Searching online for a manual for this slot machine I came across the eseries manual for slot machines from 1980-86 thanks to this wonderful site. After thoroughly searching through this manual I started wondering what the dip switches in the picture do and since the manual I downloaded only has a vague description on that topic I was wondering if you fine individuals on this site could help me with this. Also in the manual it states about the sound board but I was unsure if it had a volume switch to turn the volume up or down since the sound is very loud. Thank you in advance for any assistance and enjoy the photos of my new/old machine.
