    3D Printers and Pinball

    I attempt to model with the intent of not requiring support. I don't like post processing clean up. Some details like lofting are evident but I will also incorporate tiny layer level details to span and build a lattice work in areas that would seem impossible to print without support until close...

    TILT!Audio

    I'm putting it out there looking at opinions on lower cab speaker selection. Impedance matching aside I'm trying to figure out what is optimal for the application. The first thing that I would think is mid and high frequency sounds are far more directional than base so a woofer would be the best...

    No more reset?

    5vdc has a watchdog to reset the game if the voltage drops to the point of logic being questionable. Like coils locking on. Monitoring or using 12v negates this failsafe that is deliberately incorporated into the design for safety reasons.

    BK80: T'shooting Wonky Lamp Behavior

    I have PIA's and can burn ROMs but Dave Astill on here does and sells them as a service. I suggest if you are looking for these items he'd be the go to guy.

    BK80: T'shooting Wonky Lamp Behavior

    https://www.pinwiki.com/wiki/index.php?title=Leon_Borre_WMS_System_7_Repair Apparently the file to burn his EPROM on a 2532 is here long after sadly he is not. Here's another tool for the toolbox that can test the lamp matrix isolated to the board...

    BK80: T'shooting Wonky Lamp Behavior

    Could be a simple as a bad lamp diode. You might count up the funky ones and see if there's a common column or row. Could be a wonky 6821 PIA for the lamp matrix on the driver board. If they've been worked on and socketed it may be worth plugging in another lamp matrix PIA and see if the problem...

    Go from this to this takes ~ 10 minutes. Sound already is much less muddy sounding with just speakers but the board and high definition samples makes it far better again... The wirings are still mono for now. Then 2.1 with the board installed.

    BB speakers assembled. Will install with original hardware on factory holes. There's also always the option to buy a replacement CNC cut speaker panel with pre-cut 4" or 5.25" speaker holes for $30 USD from Michigan. https://virtuapin.net/index.php?main_page=index&cPath=17

    I have added two additional stl's here https://www.thingiverse.com/thing:5191988 to provide mounts for a pair of Pioneer TS-F1034R high efficiency 4" 2-way speakers in a WPC game. My next application of TILT!Audio will be on my TZ and I will provide an update as things progress.

    STTNG Strange Issues

    Prob trough opto board issue. Great Lake Modular. Replace/upgrade. I had nagging issue with IJ trying to get the original boards working reliably. GLM replacement never looked back.

    Floor Protection

    Porcelain tile with a PEI rating of 5. Can drag machines over the floor on their metal feed and there's no sign of damage. Having said that I use a dolly to protect the machines.. not the floor.

    WTB Gorgar speech board

    Ronnie at the time marked runs through the speech / sound circuit on a System 7; I know you're dealing with Sys 6 but it's a similar set up it would appear.

    WTB Gorgar speech board

    It would be a TDA2002. I just checked and all I have are incompatible TDA2030A's. You may be able to use a TDA2003 as well but you need to confirm this. If you touch the amp itself and you get a hum it's probably still working. The problem may be in where the speech gets mixed in with the other...

    No more reset?

    Is this a 5vdc buck converter running off the 12vdc line? If it is what I think it is this doesn't make a lot of sense to me when you're dealing with a watchdog circuit meant to protect against problems with low 5vdc logic levels that run all the higher voltage goodies in a nice dry wooden box...
