Whilst working on my 80b sound board recreation and building up the different channel sections, i came up with an idea to build a version for adding your own sounds, speech and music into a board that would still plug into existing technology. Powered by other similar technology that i am already using in some of my other projects and products here's a sneak peek of the early prototype

The idea being that you will be able to load a set of sound files in WAV format on to an sd card which will then alter what your game plays during the game etc. The games have 31 different sounds that can be played including 7 music tracks

Latest updates for my custom sound board for 80b games. Some pics of the latest revision to the proto board using some more powerful embedded controllers to handle the sound processing better. The board can now play upto 4 channels of 44khz, 16 bit, stereo sound (cd quality) sound. So that's enough for 1 music channel, 2 sound effects channels and 1 speech channel. I have the board playing the original sound effects and music from gold wings via wav file samples read directly of sd card and of course you could swap these out for original score and effects etc. The possibilities here are endless.

The board is also instant boot using embedded controllers. no computer os system boot up delays. More vids soon when i plug this into my gold wings game and play some games to test it out.

Yep, that's the plan Aiming to sell them for around £100 plus postage, though that's not finalised yet.

Still working on it. The more powerful controller i'm using now is much better. Things have been hectic with all my other hardware board sets and projects, but this is on the list.

I own a Gold Wings ! One of my fav games of all time and the reason why i started making new cpu boards and these other projects Thanks JT. You rock

The board has the capability to decode stereo sound files, but to be compatible with stock game wiring and amps it outputs a combined mono signal. I may develop a true stereo amp board that can be plugged in as a replacement though later Most pinball games though are mono and original sound files are usually only recorded in mono. A good upgrade for general gottlieb 80b games is to add another speaker to the backbox anyway just to balance the sound output and return the game to a more normal 3 speaker design.

The board has 4 channel but this is mainly for handling the types of sound and speech effects playing together during the game. i.e you can play a music backing track then 3 other sound effects potentially at the same time. The original boards hardware is very good, so that it can handle the same and not have some sounds cutting others out.

Taking this in game play terms. The multiball ready feature on Gold Wings has a high pitched bip repeat tied to a flasher to show the lane to shoot. This plays along with the background music in a 1 second repeat. However, when pop bumpers and other targets are hit they also still respond with their appropriate sound without stopping any other sound playing

Yes still working on it. Hope to update again soon

Major progress with this project. I have finally got the interface to work reliably with inbound cpu requests.

Good point in the vid is around 5.35

This project has been much more complex than first thought but we are getting there now. The sound board logic is much more than just 'play this sound Id' it turns out

I'm still refining the code logic and not 100% sure if each game will need custom logic as well as a sound file set, we will see, but the second prototype boards are getting closer. Also waiting for some dac sound processors to improve sound quality and remove noise. The first test was using bog standard passive Pwm line out

Not long! I am currently working out the best DAC system to use to get the clearest sound output possible

Yes i have been working on this alongside many other projects . Here is the latest prototype boards i got just before christmas. This is part way through assembly of it for testing. Its alot smaller than the original now but still fits the mounts ok.

Its mainly designed for a replacement of boards MA766 and MA866 but should work with other games that use flavours of either of these boards.

When i have something to share i will update the thread. I work on many different projects at once and there is only so much time in each day, plus i'm just 1 guy, not a hundreds strong enterprise like stern or something...

Please can you stop spamming my product development thread with your own experiments. I am developing a professional drop in replacement sound board for 80b and system 3 games. I'm not sure why you have taken over my thread with your personal experiments. Also the sound boards are 4 channel not 1 and they interact with each other in differing ways during game play. A simple wav trigger isnt going to handle it very well, other than for basic changes.
