LISY MPUs
What is 'LISY'? It stands for LInux for SYstem.
It is a replacement MPU for Gottlieb, Bally, Stern or Williams pinball maschines
LISY uses a Raspberry PI Zero which is integrated in a self designed PCB, used softwarebasis ist Raspbian. You can either use the original Gameplay by using PINMAME romsets or create your own Gameplay by using the Mission Pinball Framework
*********************
important note
While my 'LISY' boards ( LISY1, LISY80, LISY35 ) do work quite well in pinball games I got reports that on some games 'fast switch moves' ( like with spinners) are not detected 100%. This is due to the internal handling in pinmame (software emulation) and I do not have a solution for this yet.
For these games I do recommend to use one of my 'Fa' CPUs ( BallyFA, GottFA1, GottFA80) They are based on hardware emulation and much closer to the original CPUs.
documentation
software
What do you need?
Basic soldering skills (only one of the integrated circuits are in SMD size)
Possibility to read/write micro SD cards
Wireless LAN oder LAN if you want to use LISYcontrol
A pinball machine supported by LISY
Summary
LISY replaces your original pinball MPU
Gerber data for PCB included
You just need to buy the needed components; download and install the LISY image and do the soldering.
I do provide all the software you need for free.
The PICs can be programmed using the integrated programmer of LISY
Costs?
One PCB is around 8€, however you need to order at least five PCBs when ordering at 'jlcpcb.com'.
The needed components are around 50€, depending on where do you buy the components and what LISY variant do you want to have.
LISY is integrated part of pinmame, have a look at the source code here
List of (standard) components is documented.
As the solution is using pinmame gameplay is 100% compared to the original game Optional you can use 'Freeplay'; 'Ballsave' is still 'work to do', if you are interested in that feature please send me a mail.
There is a Webinterface integrated ( 'LISYcontrol'). This means, by connecting LISY to you local LAN/WLAN it is possible to control each lamp and each solenoid via Webbrowser. Status of switches are shown on one page, and switch descriptions can be edited in a'csv' table.
