1 Introduction

This pinball machine was manufactured in 1987 by a Spanish company, Universal de Desarrollos Electronics, S.A. Their various trade names were Unidesa/Cirsa/Stargame.

It is horror-themed and has both 2 and 3-ball multiball.

The boardset is unique and the playfield parts are as well.

The manual for the game is in Spanish. The available scans of the manual available on the internet (see the manual on IPDB) are not good quality and there are some mistakes (to be pointed out below).

2 Technical Info

There are 4 major boards that are used in this game:

• Power Feed Board (Carta Alimentacion)
• Solenoid Driver Board (Carta Potencia)
• CPU Board (Carta Control)

The game used LED displays and there are 4 displays for the players and a credit/match display. As a result, there is not high voltage generation in the machine.
