This is an upgrade 2 chip set for the collectable full-size arcade GRAND PRIX pinball.
It is the latest version of CPU .450 and DISPLAY .400 available from the manufacturer (now Stern Pinball).
This auction is for the 2 chips and the service of burning the images onto the chips. The software on these chips is not owned by me but is made available for free from the manufacturer to the public.
These do fail from time to time.
If your game does not work it may be these.
Great to replace your missing or damaged chips.
When you first power up the game and enter diagnostics, the display tells you what version of software you are running.
The manufacturer recommends using the latest version available.
Many of these pinballs are being reimported from overseas and the ROMS are not in the English language. These chips will convert the language back into English.
I also have the SOUND ROMS for this game.
