Paragon
Bally, 1979I'm entertaining modifying my own Paragon with quips I'll voice myself. I think it's possible with a little circuitry adaptation. What do you think? (Note: I'm a professional broadcaster who could swing a mean voice. I would need a female voice to parallel the characters.)
Here's one way... I plan on doing something similar myself someday.

That's amazing! I don't aspire to such greatness, and I'm pretty sure I'd rather use the original switch matrix. At any rate it's a pipe dream at the moment.
I've decided that adding background music would be better than just simple voice-over work, but the things I intended to add could be added to the music tracks triggered by various Paragon switches. Here's the breakdown of what I envision if I could manage to get a copy of the music supplied in this YouTube video:
:47 - Start Game
6:50 to 7:35 - Ball Plunge and standard gameplay loop
7:35 to 8:05 - Paragon saucer ready loop
15:31 to 15:47 - Waterfall sequence mixes down to gameplay loop
58:44 to 1:00:00 (or so) - Golden Cliffs saucer @ 20K loop
1:03:11 to 1:03:37 - Game over
...and the really fun one...
45:47 to 47:17 - Valley of Demons saucer (find a way to keep ball from ejecting until 46:16) sequence mixes down into either standard gameplay or Golden Cliffs loops depending on situation
I expect I can closely match the voiceover of this part of the track to say "The Valley of Demons is open" after the in-line drop targets have all been hit.
Well I think I could make this happen for about $100. $50 for the MP3 trigger, $30 for the speaker set, and a couple other odds and ends.
QUESTION: Can I tap off the original switches to trip the MP3 triggers? Seems like I ought to be able to as long as I put a diode on the positive lead to the MP3 trigger board.
I did a Three Stooges custom pinball machine with speech a few years back. I used chipcorders and wired up the playfield switches to a DPDT relay. Using a +12V supply, the playfield switch would close the circuit for the relay coil, closing two sets of contacts. One set of relay contacts went to the original playfield wiring (be sure to include the diode) and the other contacts on the relay triggered the speech from the chipcorder.
Quoted from Mk1Mod0:Don't know. Must be a reason they didn't. Over my head there.
Didn't do what? Add background music? Technology wasn't there yet.
Tap off a switch? They didn't have to, Bally designed the game. Had they been in the business of putting music in they would have incorporated it into their sound board to begin with.
Quoted from travisbmartin:Eric_S, is it possible to use an AND circuit in reverse to do the same thing as a DPDT relay?
I'm sure it is possible to do the same thing with solid state components, but I don't think an "AND" circuit is what you're looking for. In the Three Stooges, I used a summing amplifier circuit to tie all of the sound outputs to the same speaker.
Thanks for posting the schematic. I have a Gottlieb Time Line that I'm planning on rethemeing. I'm obviously wanting t change the sounds and music, but I don't want to wire secondary switches everywhere.
Deckmanmark,
Here is a free website that lets you down load the sound track from a youtube video as a MP3 file.
Just copy the url of the youtube video into the field and click the convert video button.
And if I remember correctly the Ghostbuster pin used separate switches to avoid frying the mp3 trigger broad.
The youtube mp3 site only supports <20 min. video lengths. Doesn't work for the track I was attempting to pull from. But maybe I search for smaller clips that would satisfy.
I did use separate switches for GB, but there are other ways this could be done. Just simply connecting the MP3 trigger to the game switches is going to blow some fuses or worse. I have seen some people use opto isolators to split the switch closure into two different signals. This seems to work well, but is somewhat costly. I wouldn't be surprised if there are other ways too. I just went with what seemed like the simplest way to get results at the time. I'm no technological guru.

The main reason I feel there is a need to use game switches is that there are modes of game play that I would like to incorporate different music to, and would only be accomplished by using the logic coming from the MPU. It may not be possible without some significant engineering. My theory is actually not to attach the trigger to the physical switch, per se, but somehow route end result MPU pulses to the triggers.
