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 used in this game:
- Power Feed Board (Carta Alimentacion)
- Solenoid Driver Board (Carta Potencia)
- CPU Board (Carta Control)
- Sound Board (Carta Sonido)
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.
The basic architecture of the game's electronics is:
- The Transformer sends various A/C voltages to the Power Feed Board
- The Power Feed Board turns most of these A/C voltages to D/C voltages through the use of 4 bridge rectifiers and sends those voltages to other boards in the game. Also the Power Feed Board holds most of the fuses on the game (the only exception being the main fuse, which is located in the bottom of the cabinet, next to the transformer).
- The Solenoid Driver Board is responsible for driving the solenoids (actually coils and flashers) in the game.
- The CPU Board runs the game code and is responsible for driving the displays, the feature lamps, and handling switches
- The Sound Board generates sound and speech
