Brunswick / Briarwood
 |
1 Introduction
Brunswick, the large American manufacturer of bowling equipment, had already been making some coin operated amusement equipment such as Air Hockey. In 1976 they decided to venture into the new and growing home pinball machine market. At first they used their Briarwood name on the machines, but as sales started to increase, they switched to using their Brunswick name for better brand recognition. Brunswick made several home pinball machine models between 1976 and 1980 not only under their own name but also for the Henry W.T. Mali & Company (world famous make of pool table cloth and billiard supplies).

The EM version of Super Star has four Gottlieb 2" flippers.
Brunswick made the Mali "Diamond Jim" machine.
3 Technical Info
The Briarwood/Brunswick/Mali home pinball machines were covered by the now expired patent number 4109916 in which one coil mechanically operates two devices. In this case it is the slingshots and pop bumpers.

4 Problems and Solutions
4.1 Power Problems
The power supply assembly of Aspen, Alive, and the 4 player Circus contains power transformer, 4 circuit breakers, 2 bridge rectifiers (one powers the solenoids, the other powers the gameboard and lights), and a 24VDC relay that cuts off power to the solenoids.
4.2 Solenoid Problems
All coils operate on 24 to 28 volts DC.
4.3 Lamp Problems
4.4 Switch Problems
4.5 Display Problems
Check the pins of the display assembly closely for signs of cold solder joints and resolder any if found.
4.6 Sound Problems
Early Brunswick machines used a bell unit and a single tone chimebox for sounds. Later machines such as Alive and the 4 player Circus used electronic sounds and a speaker.
4.7 Flipper Problems
The flipper assemblies in Alive, Aspen, and the 4 player Circus are classic Stern Generation 1 units with a Brunswick 55-101725 flipper coil installed. The flipper assemblies in earlier Brunswick/Briarwood and Mali machines are classic Stern Generation 1 units, but with an ordinary momentary duty coil (55-101025) with a 20 ohm, 25 watt resistor connected to it via the end-of-stroke switch. This makes an ordinary coil work like a real flipper coil, but it gets hot quickly and the coil can be noisy in operation. It is suggested to convert the old 55-101025 coil & resistor setup over to a regular flipper coil such as Brunswick # 55-101725 for better operation.
In the early Brunswick machines like Super Star or Rodeo, only one flipper unit was installed. It had a linkage attached to it so that one flipper coil could drive 2 or 4 flipper bats. This was not very good as the slightest wear or slop in any part of the linkage would make the flippers weak or sloppy feeling.
4.8 Pop Bumper Problems
In the early Brunswick/Briarwood machines such as Rodeo, there are two pop bumper spoon switch assemblies. Each switch assembly is different, though. One switch assembly has a spoon switch and a scoring switch while the other switch assembly is merely a spoon switch only. These early machines used a 55-101025 coil. The coil bracket is Williams # 04-10888 or B-7417. The rod & rings of two pop bumpers were mechanically linked to one coil on the early Brunswick/Briarwood/Mali machines. Alive, Aspen, and the 4 player Circus used the usual individual pop bumper assemblies.
Early Brunswick machines used a metal bar to connect two rod & rings to just one coil.
4.9 Slingshot Problems
The slingshot kicker coil bracket is a Williams # A-17808 or B-7572-1 "Z" bracket in the Alive, Aspen, and 4 player Circus machines. Earlier Brunswick machines such as Rodeo used Williams # B-7417 or 04-10888 pop bumper bracket as the slingshot kicker coil bracket.
