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. | In the early Brunswick/Briarwood machines such as Rodeo, there are two pop bumper spoon switch assemblies.

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, the world famous manufacturer of pool table cloth and billiard supplies.
2 Games

4 Problems and Solutions
4.1 MPU Board
This is the game CPU board used in the 55-860200-2 version of Aspen. This version had a chimebox in the game cabinet for sounds. Notice the presence of the infamous "spider" chips just like Gottlieb System 1 pinball machines had.
The CPU board in Alive also used the "spider" chips. Brunswick was smart in that they had them in sockets for ease of replacement.
The 4 player Circus MPU board is similar to the Alive board except that the Game Over light has been removed and a jumper wire run to the edge connector. This allows the Target #1 lamp to be addressed by the board. Notice the socketed "spider chips" and other chips.
4.2 Power Problems
The power supply assembly of Aspen, Alive, and the 4 player Circus contains power transformer, 4 circuit breakers (3 in Circus), 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.
The original bridge rectifiers are type BR-62 (6 amperes @ 200 volts). You can step up to the better NTE 5314 or Radio Shack 276-1181 which are both rated at 8 amperes @ 400 volts. Even the 25 and 35 amp bridge rectifiers used in the later Williams pinball machines can be used. With the "wire lead" style rectifiers, form a loop at the end of the leads with needle nose pliers to make it easier to attach the machine's wires to the rectifier. Be sure to apply silicone heat sink grease to the base of the new rectifier. The original rectifiers were underpowered for the job and failed alot.
4.3 Solenoid Problems
All coils operate on 24 to 28 volts DC.
4.4 Lamp Problems
4.5 Switch Problems
The tilt assembly in the 4 player Circus is a conventional plumb bob tilt.
4.6 Display Problems
Check the pins of the display assembly closely for signs of cold solder joints and resolder any if found.
4.7 Sound Problems
Early Brunswick machines used a bell unit and a single bar chimebox for sounds. Later machines such as Alive and the 4 player Circus used electronic sounds and a speaker. The 4 player version of Circus uses a 4" round 8 ohm 1 watt speaker.
4.8 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 or Gottlieb A-20095 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. The cabinet flipper buttons are both wired in parallel with each other. Pushing either flipper button operates the flipper assembly to move both flipper bats at the same time.
The early Brunswick flipper bats are actually Gottlieb blue flat top 2" units # A11242-3A Blue plus # A6888E Thin Shoe & Shaft plus Screw # HDW-632-1-1/4.
The flipper assembly on a Circus 4 player machine is a clasic Stern Generation 1 unit. Replacement coil is a Brunswick 55-860235-000 or 55-101725.

- Flipper Plastic Bushing, Stern # 4A-111-W-1
4.9 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.
Circus 4 player used the same plastic pop bumper assembly as Stern "Flight 2000" did including the same plastic rod & ring. Classic Stern or Data East pop bumper parts will work for replacements. The pop bumper coil used in Circus 4 player is directly operated by the high current spoon switch contacts much like an electromechanical pinball machine. That means if the spoon switch gets stuck closed, the coil will burn up. The other switch on the pop bumper assembly is merely a scoring switch to signal the game board to register a score. Brunswick coil numbers 55-102090 or 55-101025 are replacements. You can also use a Williams AE-23-800-01 coil.
Circus 4 player pop bumper parts list:
- Complete Pop Bumper Assembly, Stern # B-695
- Plastic Base Assembly, Stern # B-695-1 or Data East # 545-5100-00
- Plastic Rod & Ring Assembly, Stern # B-695-3
- Plastic Yoke Top, Stern # B-695-4
- Plastic Yoke Bottom, Stern # B-695-5
- Coil Stop Bracket Assembly, Stern # A-186-1
4.10 Slingshot Problems
The slingshot kicker coil bracket is a Williams # A-17808 or B-7572-1 "Z" bracket in the Alive and Aspen machines. Earlier Brunswick machines such as Rodeo used Williams # B-7417 or 04-10888 pop bumper bracket as the slingshot kicker coil bracket. Notice in the early Brunswicks they only had one switch to activate each slingshot instead of the usual two switches in normal pinball machines. A person could use a 3/8" Forstner drill bit to drill the second hole and add a second activating switch assembly.
The slingshot assembly on Circus 4 player is a completely plastic assembly made by Wico. It is very difficult to find these assemblies today so it is best to convert to individual Williams, Bally, or classic Stern parts instead. The slingshot switches on top of the playfield directly operate the slingshot coil the same as on an electromechanical pinball machine. If either of the switches get stuck closed, the coil will burn up. The switch under the playfield is the scoring switch which signals the game board to score points. Replacement coils are 55-102090, 55-101025, 55-101741, or 55-860236-000. A Williams AE-23-800-01 can be used.
4.11 Outhole Problems
The ball return kicker assembly on Circus 4 player appears to be either a kickback unit or a knocker unit. It is operated from the game board.
