    PacMania - music, but no sounds

    Interesting! I did buy it on ebay - since it wasn't working correctly, I put the old chip back in. What i am hearing is that maybe I should try to source another one of these after i get the board back up and to its booting state. Matt

    PacMania - music, but no sounds

    Ok - so it looks like i damaged these 2 traces on the left (I will DEFINETLY be using the hot air method from now on to remove chips!) Of the two lines - the one on the outside - goes from chip L3-pin 16 (the trace goes under N3) to S3-pin 6 (via the via) - I repaired that. The other line -...

    PacMania - music, but no sounds

    I see what you are talking about - I will have to figure out where that was going, and check continuity.

    Namco 2X6-Pi Multi Selector

    There is already a 3d printed mount for the ODE that sits it back a bit in the enclosure - I am hoping it all fits together nicely.

    It looks like the amazon link for the OLED display is out - this one looks like the same specs - it should work...

    Namco 2X6-Pi Multi Selector

    Very excited about this! Just ordered the boards and will pick up the other parts.... :) I will have (1) extra after I am done building these - if anyone is interested.

    PacMania - music, but no sounds

    Well - I put in a new chip - its marked as a SN74LS04N - compared to the 74LS04P that was in there - does the P vs the N make a difference? I know it does on transistors. I was able to get the via soldered onto pin 12 - so continuity to RAM U3, pin 22 is good. I ran a wire on the back that...

    CPS2 I/O Interface

    In case anyone is looking for the JAMMA edge connector (PCB mount) to make their own - they just popped into stock here: https://www.memotronics.com/jamma-56-pin-arcade-card-edge-connector-socket-pcb-mount-3-96mm-0-156/ Matt

    Namco 2X6-Pi Multi Selector

    I think one that would just mount nicely in the space to close it up would be awesome....

    Namco 2X6-Pi Multi Selector

    I want to get this going and think about a way to mount it nicely in the 5 1/4 slot.

    Namco 2X6-Pi Multi Selector

    Looks amazing! I assume you can also use the buttons on the selector itself to choose the game?

    PacMania - music, but no sounds

    A better picture - I can see it better now - it looks like the trace that connects TO pin 11 from the via just above N4 is broken - not sure if I did that by removing the chip or not, but it seems as if that needs to be wired back up. Once i get confirmation from the geniuses here - I will try...

    PacMania - music, but no sounds

    Ok - I pulled out P4 - and noticed 1 trace that I need to try to get back onto pin 12 (the long one at the top of the picture) but there is a trace that is loose underneath the chip also (right by the S) - that I am not entirely sure where it came from - its coming from pin 11. Edit: It looks...

    PacMania - music, but no sounds

    I did not! Is that a very specific chip, or just search for 74LS04 ? Matt

    PacMania - music, but no sounds

    I put the old YM2151 back in, and it is back to "normal" which is to mean the sound CPU is not running. If anyone has experience with these boards, or just more experience than I have - and is willing to do some troubleshooting for hire - send me a DM. I have hit my limit I think on what I can...

    Namco 2X6-Pi Multi Selector

    Exciting! If you need another tester, I am more than willing.

    PacMania - music, but no sounds

    I got the Ym2151 late (today) but just soldered the new one in. I have a feeling its slightly different somehow - since when I boot the game I get garbled static basically. And when I go into the test mode I still get "SOUND CPU NOT STARTED". I will likely solder the old one back in. The...

    WTB: CPS-1 Dash game (doesn't matter) with HDMI mod board installed

    I keep fighting with mine - and the audio stopped working entirely on the board now, so I just want one that works so I can get ready for the Multi. Thanks! Matt

    Namco 2X6-Pi Multi Selector

    are you using a rpi3 or a pizero? I would expect any would work.
