This is an OPERATING SYSTEM 8 (OS 8) chip for the Stern Whitestar pinballs. 

This is only needed usually when boards are changed between games. 

Stern released a service bulletin 157 detailing the information.

This auction is for the chip and the service of burning the images onto the chip.

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 can provide ROMS and EPROMS for all pinball machines. 

I also carry pinball security chips, 5101, 6116, 6264, 6800, 6810, 6821, 6502, 6532, and many more hard to find I.C.’s for old pinball machines. 

NO matter what the shipping calculator says, I will combine shipping. Up to 8 chips will ship for the price of one auction.
