Cool, glad to hear this is still alive. I have a Cleopatra that I would love to throw one of these in and have some fun with MPF adding some extras to it.

LISY version 4.07 is released today, together with mpf version 0.50.9 it has a big improvement on the sound implementation.
In addition to control the Gottlieb soundboard you can play your own mp3 files or use the 'text-to-speech' feature.
Have a look at the new manual on http://www.lisy80.com and the LISY description on mpf website ( http://docs.missionpinball.org/en/latest/examples/lisy/index.html )
You will also find a BOM for LISY80 ready to order your components with Digikey ( LISY1 BOM will follow ASAP )

I think the idea would be that you install MPF on another PC and hook that to the LISY board, using it to interface with the game. At that point you can hook up whatever displays + speakers, etc you want directly to the PC

Okay... I got a question. Do you need to run this from a pc? So, that means that my pinball machine would need to be tethered to a pc to run the custom code. Or that I would need to build a pc rig inside the pinball unit. Or am I understanding you all wrong.
Because, I would love to be able to mess around with this product. But, I fear this might not be right for me. As I still want the machine to be an independent machine and not tethered to anything else.

My understanding:

Using the original segmented displays, you only really need to tether a PC to it for development purposes (developing directly on the underpowered Pi would be painful), and it will run the result 100% on the Pi after you copy the finished setup to it. In order to run anything with the MPF Media Controller (DMD or Video), then it needs to be run on an "external" PC, as the Pi doesn't have enough horsepower to run the Media Controller alongside MPF. My understanding of the latter is that something like a NUC should be powerful enough to do that.

I've got a board on the way to me, and I'll probably go the "segmented display" route and use it to enhance the existing Solar Ride within the limits of the hardware. I'm expecting that I'll be able to duplicate some of the functionality of a Pascal or Ni-Wumpff with few problems, and it will be a good way to experiment with the platform for future pinball experiments, plus the original game is just a dip switch setting away.

Okay... I think I get what you're saying. And yes I think having it tethered to a pc during the initial coding process is smart. And I don't have an issue with that. It's just after you've finished, I just want to make sure that it can operate on its own.

Time for another stupid question. Is this compatible with the new pi 3b. I don't own a pi 3b yet. Buying one soon as they finally updated the code for retropi. I actually currently own two pi 3s. But, I'm going to stop buying the normal ones and go with 3b's cos they're a bit better. Just an itty bitty bit.

I thought I was done with my stupid questions... But, stupidity knows no bounds... At least for me. Anyway, I am thinking about altering the code for a Raven pinball. Which is a gottlieb system 80b. Is that supported. I'm hoping it is. Cos I got big plans for my Raven.

Got my LISY1 in, built it, and installed it in Solar Ride. Got a couple of minor issues, one with a switch (rollunder won't register, will need to make sure my switch connector isn't failing), one with the sound (seems to be running a MUCH longer pulse running the ROM, so it sounds pretty different), but neither one is serious compared to what I was expecting to revisit with the battery damaged MPU that was in there.

Hopefully this next week I can get a computer set up nearby to start fiddling with MPF on it.

Short update: I just uploaded a new version ( v 4.09 ) of LISY image to www.lisy80.com
With latest mpf version (0.50.21) this solves a bug around switch detection when using LISY with mpf in Master Mode

Did any of these boards ever end up getting over to the US? Or is the best way still to order straight from Germany? Just picked up a Genie and I sense a lisy in its future

Ordering from him is still the best way to get one, since it's really more of a diy programming kit than a drop in replacement, although it'll run the original ROM file in a pinch. I've been fiddling around with mine; in fact, I'm the one who alerted him to the switch detection bug in the MPF side.

Note that replicating Genie's ruleset might be a lot easier than Solar Ride's; The shot advance routines for the bonus multiplier had me running around in circles making sure everything would advance only when called for, and all uniformly.

I'll probably just make some custom rules not a fan of genie's. I was just hoping to avoid international shipping.

I JUST found this! Been needing a few sys1 cpu boards. I have a question though. One of my sys1's has a bad small transformer, so I'm about to lose the 69v etc. What voltages are required to power the cpu/pi board? There is a theory I may have to test of using a new cpu board and led displays with no small transformer.

So the roms for gottlieb's is difficult. I have the games, is there a reader so I can get to pull the rom into a rom file. Or do the visual pinball files have the roms in them?

I believe the board only needs 5V. The bigger issue you're going to run into is loss of the displays, since the 69v is the main drive voltage for those. It might be time for you to get a set of the Boston displays, as those don't need the 69v.

Archive.org should have the ROMs in one of their MAME archives.

International shipping wasn't bad. I received my example pretty quickly.

Nice! Ya that is the plan. Led displays and a new cpu board. I think @forceflow had a theory write up, and I’ll be trying that! Not sure if anyone has tried it successfully yet.

Archive.org, didn’t even think of that. I’ll check! Thank you.

Pretty excited to get a handful of sys1’s working again

Not finding the roms :/

lisy1 is on its way!
