“Tricky Traps” restoration

Loading

In this post, I’m going to take a look at the restoration – or rather repair – of a handheld game that I recently received for review. It has the name “Tricky Traps”. This means something like “tricky or tricky traps”

The game “Tricky Traps” by Tomy is a mechanical game of skill that was originally released in the 1970s. It consists of a maze-like playing field in which the player must navigate a small metal ball through a series of obstacles and traps. The aim of the game is to successfully maneuver the ball through the maze to the finish without it falling into one of the many traps. There are five balls available. The game is timed.

Tricky Traps

Game mechanics:

  • The player starts the game with a rotary knob, which sets a small electric motor in motion. This motor drives the “traps” and also the rotary knob itself via a gearbox. This is how the “timer” is realized. Once the rotary knob has completed about three quarters of a turn, the motor stops again and the game is over. This is solved by a contact spring, which is pressed down onto a mating contact by a small bar at the bottom of the rotary knob.
  • Once the game has started, the red button can be used to release a ball into the track. The white button at the bottom is the actual and only game button. It lifts the ball with a small cylinder so that it can move through the various parts of the playing field. You have to do this with the right timing.
  • There are numerous obstacles on the playing field, such as rotating disks, small ramps, narrow passages and a rotating magnet that can stop the ball or cause it to fall into a trap.

The colorful design is typical of the mechanical games of the 70s and 80s. It is made of plastic and the moving parts are usually brightly colored.

The technical problems that occur often in such old games are:

  • leaking batteries, which usually cause corrosion and destruction of the contacts
  • Brittle plastic, which mainly occurs with gearwheels that are mounted on brass shafts and therefore start to slip. This also means that housing gears often no longer hold together properly.
  • Electric motors whose brushes are worn so that they no longer turn
  • Resinous grease and oils that make moving parts sluggish
  • Wires and electrical connections that are corroded and broken

All of these points can be found very often during restoration and must be fixed. This can also be done more or less easily. After carefully opening and inspecting the appliance, I actually start by completely dismantling and cleaning the parts. Then I try to repair any broken plastic parts. Here I use various adhesives as far as possible. Sometimes it is also necessary to reproduce a part with a 3D printer. Of course, this assumes that enough of the original part is still available to reconstruct it accurately. The electrical components of these devices are the easiest to repair, as there are usually no electronics with any components with ICs that are no longer manufactured.

Tabletop game console Galaxy II

Loading

“ASTRO WARS” or “GALAXY II” is the name of the table top game console that I am introducing here. It is the home version of the arcade game “Galaxian”, which was implemented as a small tabletop device for everyone at home. The manufacturer was Epoch, which sold the device in 1981. There was also a clone made by Grandstand under license from Epoch. The device was named “ASTRO WARS”

As was the case with many game consoles back then, the technical structure is a “stand-alone” console. This means that the device could be operated without any additional accessories. You only need four 1.5V cells or a 6V plug-in power supply. The display, i.e. the display, was implemented using VFD (vacuum fluorescence display), as LCDs were still expensive at that time and were only used as clock displays due to the low power consumption.

The screen is designed in such a way that a curved, transparent film, printed with space motifs, is placed over the VFD tube. A Fresnel Fresnel lens shows the display content optically enlarged. The display also appears in color or shows the game symbols in color. This was solved by sticking colored foil over individual areas of the VFD tube. This gives the entire design of the ad a certain 3D effect.

From the original advertising text on the packaging:

“Ultra-modern arcade excitement is now yours, as you defend your earth ships against a fierce invasion. You must dodge the enemy missiles and fire back at the squadrons of attaching fightes, warships and enemy command ships. If you survive, you can attempt the exiting DOCKING MANOUEVRE and earn extra points.”

Die hochmoderne Arcade-Spannung liegt jetzt bei Ihnen, wenn Sie Ihre Erdschiffe gegen eine heftige Invasion verteidigen. Sie müssen den feindlichen Raketen ausweichen und auf die Staffeln zurückschießen, in denen Kämpfe, Kriegsschiffe und feindliche Kommandoschiffe angebracht sind. Wenn Sie überleben, können Sie mit dem aufregenden Docking Manöver zusätzliche Punkte verdienen.

To the technical structure:
As already mentioned, the structure is based on a fluorescent display, which in turn is controlled by an NEC D553C microcontroller / processor. This 4Bit 42PIN IC in the DIP housing is one of the chips used very often in game consoles at that time, as it not only contains the game algorithm, but is also able to control the display directly. There is also sound that is output via a piezo. The chip only needs a power supply. The clock is generated with an external resonator … a more detailed description can be found in older articles.

Update 2.2.2024: At the request of a blog reader, I measured the dimensions and shape of the “front screen” of the console.
