Before You Get Started … Stop!
1. Does your new game package include all listed parts? (Is it complete?)
2. Is the game you have chosen to transform able to supply all the required voltages for the new game?
Note: Some games, (i.e. Ms. Pac Man, Galaxian, etc.) regulate their voltages on the main PCB This makes the existing power supply inefficient. These games will require a change in power supply for your new game. Many game supply houses can offer you a switching regulated power supply for a relatively low cost.
3. Is the monitor configuration compatible? In most games it is rather difficult to change the monitor from a vertical mount to a horizontal mount. We recommend you choose a game cabinet with the same mount as your new game requires. Do you have the necessary tools? (See the recommended tool list)

Optimize Your Profits
Thorough Research shows that two and a half minute games both satisfy players and also keep the quarters flowing.
If games aren't running about two and a half minutes long, then collections probably aren't at their peak. You'll want to tailor your game to your location. The trick is to adjust a few DIP switches. (See the chart in this book.) It's easy!

Something To Think About
Your final product will be a new game.
You have made a wise decision to transform a game that has seen better days in the all important cash box into a new game. This is by far the most cost effective alternative to maximize the return of your initial investment. All you provide is the cabinet with a power supply and a monitor. Oh yes, you will need a touch of elbow grease. And that's it! We provide the rest. The end result is ... a new game at a very low cost.
Fact: Spend a little time on the cabinet's appearance (i.e. marquee, control panel and cabinet graphics). With a little paint, some wood putty and new lights, you will raise the profits of any game ... especially with the introduction of a new game package.
The new game look should always apply to the inside of your game as well as the outside. A few wire ties and shrink tubing on your harness; some fastening hardware on your subassemblies and a sweep with the ol' vacuum cleaner will ensure that unnecessary glitches do not occur.
Remember: You are creating a new game.
If you have any questions or just need some advice on any of your new game transformations, don't hesitate in giving a member of our technical staff a call.
Let's Get Our Hands Dirty
Preparing the Original Game for the New Game
Remove the following:
I would recommend painting your cabinet to give it a fresh new look. You may consider having an auto body shop take care of your painting needs.
If your cabinet has wood grain sides; remove old graphics and adhesive (adhesive may be removed with lacquer thinner. If you intend to use your original plexiglass, be sure it is in mint condition or it should be replaced.
Thoroughly clean out your cabinet.
Time To Install Your New Goodies
Before You Start ... Remember DO NOT Do This Work With The Power On!
Logic P.C.B. Cage
Mount the logic board securely (away from power supply).
A. Mark and drill pilot holes (3.32").
B. Install the P.C.B. into cabinet. Use feet and spacers supplied and adjust them so that the screws will go through the holes in the cabinet.
Attach the wire harness connector to the main logic board. CAUTION: Sometimes the connector is not keyed and it is very easy to install it reversed on the logic board. Even if it is keyed, always triple check to be sure the wire inputs were connected correctly to the connector and the connector to the logic board.
Connecting the Wire Harness to the Existing Wires
When you hook up the control panel, power supply, monitor or other subassemblies that remain in the game cabinet to your new wire harness, try and use their existing secondary connectors.
You will be connecting the wires designated for the RED, GREEN & BLUE video guns along with the SYNC & GROUND wires.
NOTE ... CONCERNING SYNC:
Your now game only calls for one sync wire connection, this is called composite sync (horizontal and vertical tied together). This composite sync is also negative. Most monitors have supply positions for both negative and positive sync. You can check your monitor manual or call our technical department for assistance.
Find the two wires that are designated for the speaker and hook 'em on up.
Coin Door Wires
You are almost done with the electrical connections of your new game. All you have left is the control panel wiring. But we are going to hold off on that for right now. We have a few other things we need to do first. So why don't you go ahead and get yourself a drink of water and stretch your legs. When you return, we can take a fresh look at your progress and then move forward.
Don't worry All this means is that you are ready to apply power to the system for the first time and you pray that there will be no smoke from a simple oversight. You are just about ready to power up the logic board. But first we need to recheck your work.
Time to Apply Power:
- Is the picture In sync?
If your picture has the top and bottom halves of the screen reversed and it will not stop rolling, change your sync polarity on the monitor. (Positive to negative (see tech tips section).
- Now how's your picture?
* It it centered?
* Is it too bright or dim?
* Is it in focus?
Check your monitor manual for these adjustments. If your screen looks "off", then your new game transformation may have been in vain. So let's take the time to make the monitor look great.
- Is the picture upside-down?
Refer to your monitor manual - switch two horizontal yoke wires and then switch two vertical wires. (Pull the pins in the connector on the monitor P.C.B. to switch them.) or check Dip Switch Tables
Control Panel Assembly
Using the original marquee as a template, Center your new game marquee graphics and score the new marquee deeply to fit the cabinet. Break off the excess with pliers. Note: when cutting marquee to size, check to make sure that you are cutting as little of the necessary art as possible (name, manufacturer, etc.)
Be sure the light behind the marquee works. Everything should always work on a new game. Take your time... Don't forget this is going to be a new game.
Side Graphic Installation
Well, that's about it. Good Luck.

Star Tech Tips
We are grateful to Star Tech Journal(tm) for allowing us to publish the following excerpts from their journal.
1. Monitor Sync
If your monitor does not have dual polarity positions for sync, you may use one of the following methods to get your game going. CURE 1: Install a simple one I.C. Circuit on your logic board. This I.C. may be "piggy backed" on to another 7404 series chip for power by bending up all but the two power pins so that they are parallel to the top surface of the new I.C. and then connecting the power pins only to the existing chip. (See Fig. 1) Next connect the sync wires as shown in Fig. 2. (Note: Figure 2 shows a hookup for either composite or separate syncs.)
CURE 2: Used for Wells‑Gardner Video‑Sync boards with positive sync connections only. (Vertical mount board 85x140B.
Cut the traces on the solder side of the board between input pins 5 & 6 to the unbanded (anode) ends of diodes X201 & X202. Add MPSA56 transistor as follows: Collector to anode leads of diodes X201 & X202. Base to pins 5 & 6 of the video input connector. Emitter to cathode (banded) lead of zener diode ZD201. Insert a IN4148 diode ‑ cathode to the emitter of the MPSA56 and anode to the base.
2. Horizontal Tearing
CAUSE: The negative sync signal of most logic sets are slightly different than the G07‑CBO monitor negative sync inputs. The result of this mismatch is a horizontal 'Wave" or "curl".
CURE 1: On the monitor deflection board, replace C 303 with a 10uf 25V radial lead capacitor with the positive lead towards the collector of X305. (CAUTION: be sure to check this step as the original cap is not polarized.) Then replace C501 with the cap removed from the C303 location.
CURE 2: Connect 1N4148 fast‑switching diodes across both the positive and negative sync inputs to the monitor. (See Fig. 4) NOTE: Both diodes must be installed or you will not have vertical stability.
CURE 3: Join negative sync inputs J2 and J3 together with a jumper. Locate WI02 and install a jumper from W102 to either J2 or J3.
CURE 3: For Wells-Gardner K4600 series monitors Replace C356 (47uf 25V) on the Horizontal/vertical board (vertically mounted board nearest the flyback transformer) and center the horizontal hold pot. Turn L351 for the best horizontal stability and fine‑tune with the horizontal width pot.
