This is a black and white game with a green layer on the screen. Game rules are very simple: the player drives a bumping car inside a maze full of “dots”. Each time it passes on a dot, the dot disappears by crediting points. The level ends when all the dots disappear and the maze is completely clean. The game would be simple if there was not another “enemy” bumper car to turn in the opposite direction whose purpose is to stop us trying in every way a frontal collision.

The game was created by Zaccaria clearly inspired by Head On of the Sega. The cabinet in my collection is precisely the Zaccaria’s version restored and in good condition even if the glass shows veins on the screen printing. The control panel and the marquee are in excellent condition.

From France with love…

This is my 5th Zaccaria’s cab. Actually I already have a Head on and a Twin cocktail with Crash (Head On) / Intruder (Space Invaders) but this cab is very nice and I wanted to save it from that warehouse 🙂 This are some details. Unfortunately I had no enough space to take pics of the entire cab.

Control Panel (1) – Cleaning and disassembling

12 November 2015

Here is the CP. It was very dirty but not so much damages under the dust.  Joystick was rusted and CPO had some cigarettes burns.

Disassembling all parts I could see part of the CPO art was damaged and I used acrylic colors. The wood had some scratches and I found a spray with a very similar blue.

Control panel (2) – Restoring colors

12 November 2015

Then I used acrylic colors for the overlay and spray for the wood.

Control panel (3) – Behind

12 November 2015

Nothing peculiar behind the CP, please note the diodes on the leaf switches; they indicate controls are managed as matrix.

Control panel (4) – Joystick

12 November 2015

Joystick has been cleaned in all its parts and the rust has been removed.

Control panel (5) – Reassembling

12 November 2015

As last step I removed some burns with an abrasive sponge and I put a protection behind the overlay in order to avoid the paint has a direct contact with the wood.

Coin door

13 November 2015

Coin door was dirty and rusted but not dramatically, so in a couple of hours I could do the job.

Monitor

13 November 2015

The mounted monitor is an Hantarex MT1. Not working obviously… I changed the fuse and I immediately recapped it but I had no changes. Then I changed the power transistor and the 2 other transistors on the H and V and now the monitor works. Before proceeding with monitor and board I want to finish the cab 🙂 Transistor replaced: TR6: BF460 TR10: 2N3055 TR19: BU606D

Base

17 November 2015

Cabinet base was missing. When I restored my EYES I saw the base was structurally the same for all other zac cabs; some times smaller, some times bigger. In this case it’s smaller: 60cm x 61.5cm so I used the draft I made in the past to build the missing parts. Each job needs the right tools…

dodgem045

This is the draft I made

dodgem047
First of all I cut all parts

dodgem046
I don’t want to bore you with all details you can already find here in my EYES restoration thread.

dodgem048
I used the same wheels I have under my Astro Wars so both cabs have the same height.

dodgem049
That’s all.

Inside

24 November 2015

Wasps lived here 🙂 the rest was dirty and rusted but not too much.

dodgem051 dodgem053 dodgem054  
Power supply board was rusted in some points. I changed all caps (but not the big ones) and I replaced all regulators.

dodgem055 dodgem056 dodgem057 dodgem058
Now it seems to be new…

dodgem059
As usual I replaced the fuses

dodgem060
and the power switch (I always replace the existing one with  a bipolar switch)

dodgem061 dodgem062 dodgem063
Now it is more acceptable; isn’t it?

Behind the cab and Back panel

Easy job for the dark side of the cab 🙂

PCB Troubleshooting

10 December 2015

Aesthetically speaking the board was in good conditions

dodgem068
This is the sound daughter board

dodgem069
And this is the additional board for game dip switches

dodgem070
but once I powered on I could see some problems.

dodgem071
Actually the board was in RESET so I found the reset circuit on the schematics

dodgem072
and bypassed it through the J13 jumper

dodgem073
Once done, I realized the board had mainly graphic problems

dodgem074
In fact replacing rams I had results better and better

dodgem075

Once all RAMs were replaced I had a good screen but I though the game reset again after drawing the maze. Running the game on MAME I understood this game hasn’t an attract mode so it works! So I mounted the PCB in its cabinet in order to test I/O.

dodgem076

I/O have been tested following this schematic:

dodgem077
And I followed these instructions to set the game properly.

dodgem079 dodgem078
Now I can play 😀

Complete!

Here you can find some pics of the result
