What is Ewe 22?
Ewe 22 is a functional equivalent for the original U22/G10 security PIC IC chip used in all WPC-S and WPC-95 games from 1993 to 1999.

What is a security PIC IC?
Williams developed the original security PIC as a method of electronically fingerprinting each machine. Each chip had the game's serial number programmed into it, and was displayed as part of the bootup process. This way, distributors could track an individual machine.

The chips are "keyed" to the game software itself - a PIC for World Cup Soccer will only work with World Cup Soccer software. They are not swappable with any other game.

Without the correct security PIC installed, the machine will not complete the bootup process and will report a "INCORRECT U22 ERROR" on WPC-S and a "INCORRECT G10 ERROR" on WPC-95.

Why do I need a Ewe 22? My original security PIC is working fine.
The original security PIC IC's are no longer available from Williams. If the chip fails, your machine is essentially useless. Williams never sold two security PICs with the same serial number.

We recommend that a Ewe 22 is used for daily game operations, and the original saved for later resale or to keep the game "original."

Ewe 22 is shipped in a special anti-static container which can be used to safely store the original.

Will a single Ewe 22 work in all games?
No. Each Ewe 22 is made to work in tandem with a particular game title. A Medieval Madness Ewe 22 will only work in a Medieval Madness.

Do I need any special version of software installed to use Ewe 22?
No. Ewe 22 works with any version of software. We do recommend however that most games be upgraded to the latest available.

Are any restrictions placed on the game with Ewe 22 installed?
No. Ewe 22 does not limit the game to "Free Play", or any other type of restriction. The machine will continue to function exactly as the original.

Will any of my settings or high scores be lost/reset when a Ewe 22 is installed?
No. All high scores and settings will be retained.

How does Ewe 22 differ from the original?
Each original security PIC had a unique serial number encoded internally. All Ewe 22's have a serial number of "999999 99999". This allows for easy identification that Ewe 22 is installed.

How can I tell if my original security PIC is bad?
A bad security PIC will display "U22 ERROR" or "G10 ERROR" during the bootup process.

Are there Ewe 22's available for other WPC-S/WPC-95 based games? What about Home Roms?
Yes. For example, a Ewe 22 is available for Ticket-Tac-Toe and Phantom House. Also available for Theatre of Magic V1.4H. Please inquire for any special needs.

My game is having strange coil/lamp/switch problems. Will Ewe 22 solve these issues?
No.
