GottFA80 - a Gottlieb System80 MPU based on a low cost FPGA

This is a 1:1 functional replacement to a original Gottlieb System80/System80B MPU, without the additional features of a LISY80, but with much faster boot and lower costs. You can build a GottFA80 for less than 70 Euros!

GottFA80 v4.1 complete

Version 4.1

Version 4.1 is based on the Cyclone IV board described here.

Important note: This FPGA  board is currently ( Dec. 2021 ) not available. So better check availibility BEFORE ordering your PCBs!!! ( Or in case you do not have 'late' 80B games order V1.0 below)  I'm working on a GottFA80 version with a another Cyclone IV board.

I do provide two sets of BOM and CPL files for producing the PCBs at JLC. The first set do include the PCB and SMD components only. You need to purchase the DIP components and solder them yourself. The second set do include all DIP sockets using the 'hand soldering' service from JLC. Here you only need to purchase the DIP chips and the SD card and place them on the board.

For easy replacement all chips placed at the 'corners' of GottFA80 are in DIP format.

Set1, SMD only

Set2, handsoldering by JLC

Dokumentation & Software

Due to copyrigth on Gottlieb roms the SD card does not contain any rom code, but do provide the right struture for GottFA80. Have a look at the user manual to see how you can copy your rom images onto the Sd card.

Software & documentation for v1.0

Gottlieb & Bally replacement MPUs based on FPGA. Faster boot, more compatibility (hardware emulation) but less features compared to LISY

Note: due to memory limitations v1.0 of GottFA80 is not compatible with the 'late' 80B games ( Hot Shots, Big House, Bad Girls, Bonebusters and Night Moves ).
