    The Fourplay_R2 is a totally different beast. It is designed to use a 27SF512 chip that is removed to program using something like MPTune bin stacker.
    Four tunes for LM and only two for SMEC.
    This design is not flashable.

    i know the LM setup isnt flashable, ordered a chip burner and a 10 pack of SST 512's. im building these for my buddy and his wife, they both have GLHS's, if one gets one the other will complain until they get one so i gotta build 2 lol.

    Re: Fourplay how to

    Are there only like three or four people experimenting with these setups? I actually just recently got my GLHS back up and running. My wife's might be a while. Both LMs are pre-87 dual PROM units. Crusty had said that one of these is capable of running TII electronics and the other is not, so I won't be able to run whichever one in a GLHS. If I can figure out which one can, I can test it out pretty soon. Heck I don't even know what calibrations are burned to the chips.

    I've been kicking myself for not being more organized when I pulled my Charger apart. I haven't been able to find my air box and intercooler piping from it thus far.

    On a different note; is the round switch board only there to house the digital switch and LED display? For all intents and purposes, could the fourplay board be switched by 5v outputs from a different controller such as a single board computer like a Raspberry Pi if someone were to want to get fancy?

    Re: Fourplay how to

    Yes the number of people are limited. A small team of us are working on a new better flashable design that works on SMEC, SBEC, SBEC2-377 and SBEC-652. We are getting close to solving the last technical hurdle. The PCB design V1.0 is now complete but will need testing before we release.
    The BB FourPlay modules use inverted logic. If a pin is connected to ground via a switch (or electronic circuit) it will change memory location. The 74HC148 is involved in this part of the circuit. So yes it can be controlled by Arduino or a Pi.

    I burned a Turbonator stage 1 cal to each address location on both chips just to get each running.

    the mpscilink board has a number of 5v digital pins available........ obviously you would need to put your "normal" cal in the default location in case the external 5v went down.

    btw, we are now successfully programming the new "universal" 4 play flash board using the 39sf010 chip. woohoo. more to come.
