GOSOF80 Version 1.1

Gottlieb Soundboard on FPGA for System80

Field Programmable Gate Arrays are great devices, I wanted to dig into that area a bit and of course I choosed to use it for pinball Hardware.

GOSOF80 is based on this Code I found on Github. I replaced the PS2 routines by 4 Input lines (compatible to Gottlieb ) added a dip switch to select the game and produced a PCB with Gottlieb compatible connctors.

What do you need?

The solution uses the cheap Alterra Cyclone II dev board which is available on eBay for 15€ or so.  Search for "Altera CycloneII EP2C5T144" and make sure you buy the version with seperate connectors, as for GOSOF80 the connectors need to be placed on the bottom side. Make also sure you also include order the programmer (USB Blaster) in your order.

For the Gottlieb Soundboards with spech capability ( Votrax SC-01 speech chip  ) GOSOF80 uses a cheap MP3 Player module ( DFPlayer Mini). On the SD card the speeches are stored as wav files. You can choose the original speeches or create your own!
