    Looks like the Pinsound bros are going to release a compatible CPU board for WPC systems.

    Has anyone heard anything about it yet?

    Looks like it has no more reset built in.

    Besides the "no more reset", it looks like it has some other common WPC89 board mods; changing the RAM to NVRAM, and swapping from the AA batteries to a coin (or external) battery. The RAM change looks interesting...there's another RAM chip on there too (onboard RAM).

    why not a rtc controller and ditch the battery all together, you already migrated to nvram.

    the battery is only to keep the clock time, which from what i can tell they moved to a different style clock circuit?

    the only thing that plagues this boards are battery damage and someone hitting the switch matrix with 50v coil voltage

    i don't see a crazy need for these, and being smd , not easy repair for some, unless they plan on selling for $50 hard pass for me.

    If anyone's interested, the new PinSound replacement Bally Williams boards launched today:

    Would be a lot better if it wasn't built using all surface mounted parts. Makes hobby repairs much more difficult.

    Great that there is a new product option to market though, gives people more options.

    Surface mount parts is way cheaper to manufacture (automated insertion and soldering). It's a trade-off therefore between ease of repair and cost of manufacturing

    Personally, I prefer a relatively cheap option (which is the case here, less then 200 dollars). Furthermore, failure rate on non power type circuit board is super low anyway if designed properly
