Hi,

today, we are proud to announce support for the LISY platform in the Mission Pinball Framework (MPF).
The Linux Interface for Gottlieb SYstem (LISY) completely replaces the MPU in a Gottlieb system 1 or 80 machine for less than 100 bucks.
It allows you to play your original ROM using PinMAME and to run custom code using MPF by just changing a DIP switch.
No further modifications to your hardware are needed.

Starting with firmware version 4.02, LISY can act as a hardware interface to Gottlieb machines in MPF (current dev version; future 0.50 release).
Your custom game can either run on a separate PC and connect using USB or serial (very useful during development) or it can run directly on the LISY MPU itself (no extra hardware needed).
All Gottlieb system 1/80 peripherals are supported: 7-segment displays/20-segment alpha numeric displays, switches on the switch matrix, lights, coils, coils on lamp drivers (such as flipper enable and tilt relay) and sound with the original sounds.
Furthermore, you can run the MPF media manager on a separate PC to play custom sounds or add a LCD or DMD.

Thanks to bontango for all the excellent work on the LISY firmware. You can get the hardware and hardware documentation at www.lisy80.com. The MPF documentation about LISY and Gottlieb System 1/80 can be found at http://docs.missionpinball.org/en/latest/hardware/lisy/index.html.

Shipping from Germany to the US is not expensive (2kg for $16). bontango can probably tell more about it. He is doing this as a non-profit. The hardware is about 60€ which is currently about $60. In total this would be still below $100.

You can have that with MPF. You could use a Raspberry Pi or some small embedded system such as an Intel NuC which would easily fit into the backbox.

bontango Reichelt also ships to the US. However, mouser or digikey will probably also sell all those parts.

Digikey seems to have that one. Is it a drop in replacement? https://www.digikey.de/product-detail/de/texas-instruments/CD74HCT154E/296-33132-5-ND/38320

Edit: seems to be EOL and replaced by the smd version as well by TI.

74 series parts have been around for ages so I would expect them to continue to be available.

Edit: but at least for TI only as SMD.

Afaik, the current plan is to produce and assemble the boards in China. Unfortunately, there was a delivery problem with the first batch and DHL scrapped all boards. That was like a week ago. The manufacturer is redoing them currently. I don't know the exact plan/timescale but bontango probably knows more.

More documentation is up now: http://docs.missionpinball.org/en/dev/hardware/lisy/index.html. Let us know if you find any mistakes or miss anything in the documentation.

You can control the segment displays using LISY and MPF. Additionally (or instead of you remove the segment displays) you can connect any LCD monitor (or a DMD with additional hardware) to your PC running MPF. There are very few technical limitations.

Yeah just use your notebook or PC during development. You can then later run it on the RPi. Just make sure you get LISY with the RPI3 instead of the Zero because the 3 is a bit faster. Intel NuC or the up board are other small PCs which would work with MPF-MC. Technically MPF-MC works on the PI but it will require a lot of tuning at the end.

I think so. MPF will work for sure. Since the pinout is the same I guess that LISY will also work.

According to lisy80.com it is
