I have seen that system 1 games by Gottlieb can be converted to Chimes. Can the same thing be done with older Stern games like Dracula from 1979? I am not a big fan of these early sound boards. I can imagine liking this game if it had chimes, but can imagine being annoyed by the sound board.

Has anyone done this? If so, how?

thanks,
Aaron

I think some early Sterns had options for chimes or sound board. Lectronamo is one that could use either, if I recall correctly. I'm not sure if chimes were dependent on the rom using them or if any game on that hardware could use them.

I had a Dracula and the sound was by far the worst part.

Conversely, I find the chimes on Stern Stars to be very charming and among my favorite things about the game.

It's not directly possible, as the earlier chime sterns just fired them as solenoids (not using a separate board that you could swap), but because of the design of the SB-100 sound card (where there's a separate circuit with a binary on/off input for each of the three tones) it'd technically be possible to make a new board that replicates the sound select portion (a few and gates) and connects them to transistors instead to drive chimes.

I agree. I love the early SS machines that have chimes. It is a great combination.

Quoted from zacaj:

Has anyone out there tried this? Anyone want to try? Anyone want to post instructions on how to do this?

Thanks guys for the replies.

It looks like the first generation board used simulated chimes. Is that what you hear on the Stars machine? Does Dracula have the option for simulated chimes? If you put in a 1st gen sound board would it have an option for simulated chimes?

if you take a look at this article on the SB 100 (
http://www.techdose.com/projects/Stern-Pinball-SB100-Sound-Board/346/page3.html ), you'll see that there are three mutlivibrators, each controlled by one of the gates on U7, through pins on U3. I don't have access to my Dracula at the minute to try it, but if I did, I'd connect LEDs from ground to each of those pins on U3, to confirm my understanding of how the sound board works. Each LED should come on when its corresponding tone is played. The main thing I'd worry about is if the tones last too long, and you'd be locking on the coils for a bit instead of just pulsing them, but you'd have to observe the LEDs to see (unless you have a logic probe you could use on the original board, or something). This is all theoretical, but if you do try it out I'd be happy to help. I think you're crazy though, those monotone bloops are way better than chimes!

I knew I'd find someone. I don't have a Dracula currently, but I would like one as long as I can address the sound issue. I would be happy enough with simulated chimes if that would be possible. I know buying chimes wouldn't be cheap either. The game play and art package look great to me.

I enjoy mine, even if it is trashed.. I've never found a recording of the simulated chimes, no idea what they sound like

Stars has physical chimes. IIRC, there isn't a sound board at all on this game.

I don't recall built in sound options on Dracula, but there might have been some DIP switch settings for different electronically produced sounds, but I can't imagine that sound board generating anything worthwhile that you'd be happy with. Let alone anything that sounds like chimes.

No sound board in stars:

The chimes are driven by the driver board.

Dracula uses the Rev c board which didn't have the chime emulating circuitry

How about the the stern machine nugent could chimes be add

#14 2 years ago

I have a Lectronamo and it has the sb100 board that has the chime circuitry and can toggle between computer chimes and the computer sounds with a dip switch. The electronic chimes sound like ass and make the adding machine sounds seem good.

Is it just simulated chimes? I never looked into it, but thought some early Sterns could optionally use physical chimes with the early SB-100. I'm not sure where I read this though.

I would love to have the physical chimes in my Lectronamo as it actually is a neat game and a decent player. They are simulated chimes and the highest pitch chime is grating on you. I searched out an sb100 that had the chime circuitry and once I got it I had to wonder what I was thinking.

Why not adjust the pitch?

Truthfully I haven't had much to time work on it as its pretty far down the line with as many projects as I have. It's a cool option but like a lot of the other early SS sounds it leaves a bit to be desired. Once I get started on the nos playfield swap I may tinker with the sound some more.

Q1, Q2, and Q5 are the solenoid transistors used for chimes in games "PINBALL" to "MEMORY LANE". SB-100 was used after that point. You can check to see if Q1, Q2 and Q5 are pulsed in your game like a chime solenoid should be.

Possibly the same in Stern Nugent and Wild Fyre. I think i have seen a nugent with chimes instead of SB-100 sound card.

I have a spare chime unit removed from Memory lane for sale
