This has been sitting in storage for
years taking a back seat to a lot of other projects...it's time has
Not easy to see here but besides mounting the pedal to the door there
are a few other obvious problems to be corrected with the cabinet.
The left front foot was ripped off the bottom. The 25amp low voltage
fuse was jumped out on the power supply chassis.
This cabinet was equipped with a fan, apparently all of them were not,
the mounting holes visible. The rear cabinet power switch was removed .
There was also a crack in the frame above the coin door.
Note: the original 2 bolts on the lower right, this is the area the
foot pedal was suppose to be mounted by using a template supplied
adding 3 holes.
However, on this cabinet there is a factory 1 inch hole on the bottom
under those bolts. It appears they made a change in the foot pedal
This cabinet came equipped with a AC fan to help cool the game board
area, but mostly to cool the ARIII power supply/Amp.
(so far all the ARIII boards I've seen show the boards get very hot,
the solder side discolored from heat)
If you own one of these, probably a good idea to install a fan even if
was not originally installed.
I replaced the missing AC fan with one from Ebay straight from China. I
enlarged the outer mounting holes to allow for easier installation.
Problem with it, though the specs indicated a lower than common noise
level, it sounds like a jet aircraft.
Some research and I found another fan to replace it, not
quiet but better, probably because it runs 1000 rpm slower.
Below are the fans, specs and location to get it.
This is the Fan
115 V AC
Frequency, 60Hz Current, 0.20 Amps
Speed, 2600 RPM at rated voltage and zero pressure
97 CFM Noise, 44.5 dBA at
and zero pressure, measured at 1 meter to side
Here is the Orion replacement I found.

This fan is much quieter than the previous one
Back to the game
This is the altered front cabinet door.
What the hole in the door edge was for? unknown.
The door lock for this door was intact at the top.
Here it begins
I took some time to address that foot pedal. I
completely disassembled it, replaced the bushings, e- clips non slip
surface, removed rust, painted and luricated it.
I am also creating a backer block for it to allow mounting it to the 2-
factory screws in the cabinet.
I also added a rubber non skid mat to the bottom to protect the
hardwood floor it will be sitting on when it's kit is being used.
The bushings are from a car parts supplier, they are .500 ID and
used on clutch / brake assy's in older cars.
It useds a 5k pot , verified smooth operation.
Here re-assembled (less spacer block to be added, mat added)
Here is the assy, the spacer is just a 4x6 drilled to accept the 4
It's counter sunk to accept the lock nuts. The 2 brackets are made out
of thick aluminum. and secured to the block
The mounting uses the 2 holes left by the factory. Normally this
cabinet, with road blasters installed would have a total of 5 holes
This cabinet has just the 2 holes and a large hole for the wiiring plug
in the cabinet bottom.
Besides not wanting to add more holes to the cabinet, after I just
closed a bunch, it was needed because of the cabinet height off the
Once rubber wheels were added to protect the hardwood floor it will sit
on. So now the pedal assy sits on the floor on a rubber non skid pad.
The only negative is with the Road Blaster kit installed , the pedal
must be removed to move the game.since it grips the floor.
Now on to the cabinet.
Here the side art is test fit to the
cabinet for installation.
Note: the original art though not shown was full length. I had no idea
there were different versions of side art used.
This version was purchased years ago anticipating it's future
installation .. a surprise when opened , though different, I went ahead
and used it.
It looks fine and my guess is that later versions of the system 1
cabinet used this.
Rubber Wheels have been installed for easy movement and protection of
the hardwood floor it's going to call home.
All material in the cabinet was removed with the exception of the
marquee (for now).
Epoxy filler was used to fill a hole drilled in the front used to
secure the lock box.
This area will be recovered, along with the repaired front door.
The Road Blaster CP removed for future restoration.
A Marble Madness,CP and marquee will be installed initially.
Here surface imperfections are filled
before art installation. The filler beyond the hole is removed as the
I used Wellwood filler but added the addition of wood hardener to the
surface using an artist brush.
This photo is included to show there are
variations of the cabinet.
This version uses 5 1/4" diagonal speakers. There are versions
with smaller speakers.
The correct speakers are on order.
For some reason the Road Blaster kit
installation in this cabinet included putting the pedal on the door
instead of on the right lower cabinet. The installation instructions
clearly want it on the cabinet.
However only 2 holes were provided on the front filled with bolts. The
install requires 5 holes.
The one in the center is suppose to be 1" across to allow the pedal
to pass through. (they cut and spliced the wire)
This cabinet had what appears to be a factory 1 inch hole on the right
These holes will all be filled with epoxy wood filled and then new
black vinyl over it.
I intend to just paint the back side.
the new side art has been installed, along with the front door repaired.
Because the cabinet is on angle it looks like the gap to the edge on
the art is larger than it is, it's close to 1/4"
Also the coin door was repaired and repainted and new locks installed.
All things mention above were done.
It is fitted with a newly recovered marble madness CP along with new T
The speaker grill was stripped and repainted, though not initially
noticeable there was some rust
starting under the paint in areas. As this is being written parts are
on order to rebuild the 2 trackball assy's.
The rejuvenation of this cabinet also includes the cartridges and the
control panels plus the foot pedal mentioned before.
On the road blasters this included working on control panel issues
which including all 4 switches not working.
The switches used on the version of the yoke were common to some
keyboards of that time.
There are 2 plastic pieces added to them to make up the button assy's.
Each handle has 2 of them , fire and thumb.
These "keyboard" switches have long since been discontinued.
There is at least one source as I write this.
However I decided to find out why they failed. Below are photos and
info. to help in repairing the originals.
Here is what they look like inside the handle. Sitting on top of that
white slide is an adapter to connect the button.
These are Omron B3G-S switches
The top cover is held on by 2 plastic clips (part of the top) on
Here is what the bottom looks like after the small circuit board they
are mounted to is removed.
Here the top cover has been removed along with the coil spring and
Here the switch assy is removed from the housing. Just press the
pins on a flat surface and it slides out.
Those 4 circles on the back are what is holding the 2 halves together.
Use a jewelers screwdriver and
spin it on top of those, effectively removing some plastic and
weakening the joint.
This will make it easier to separate the halves.
When clean and adjusted, re-assemble, the 2 halves, just snap them
together., then slide into housing.
Install spring clip, then coil spring, then white slide, finally snap
top cover on.
Finally test switch operation before soldering it back to circuit board
THAT'S IT. THAT'S THE PROCESS.
All four switches now work perfectly.
Here back together, normally centers, maybe the springs are a
little weak.....next time.
There is also suppose to be caps on the pipe
This details the work on the IJ board (cartridge)
This came up for sale in the middle of my System 1 project. It wasn't a
game I had considered, but there it was.
So I took up the challenge to bring it back to life.
As can be seen here, there are a lot of open sockets, though a
functional board does have some unused sockets.
This can be the most difficult type of project to tackle, often boards
like this were used to supply parts for other repairs because it is
has a problem that could not be solved for some reason. Thankfully,
this board shows no signs of physical damage.
2 custom chips are missing 1 SLAG (Syn
Logic Array Graphics ) and 1 PROM.
Other missing parts, include 10 eproms, Speech, Sound
Processor, Op Amp
Ok, First step to source all the missing parts. The eproms are
available along with their software, the Slag chip is a tall order. As
a matter of fact I didn't
with purchasing this board until I knew I could get this chip. It
is a custom Atari IC .
The seller threw in a TI Speech chip, which goes into the board near
bottom edge on the right.
Steph from HobbyRoms in Canada wrote a replacement
for missing the prom.
All the eproms on the board were tested, those that did not verify
against the mame file dumps for this game were replaced.
A number of the eproms as found were in the wrong sockets. This board
appears to be the latest version made, having the last software version.
This was one of the stumbling blocks on this, the Indiana Jones manual
doesn't detail the version of software used on this
Possibly an official addendum was issued on this cartridge by
Atari, however I searched and could not find one.
I needed to know which chip went into which socket, I figured it
I took it upon myself to add the info to the page in the ml showing
which chips were used and the sockets they are installed in.
Here is a updated page 5-6 of the Indiana Jones manual
Click on it for full size
The last column of the program part numbers applies to this cartridge.
It is included here for those that may run into the same issue.
(If someone reading this page has an official addendum from Atari
about this change, please email me, I will add it to this page.)
Initially, after all the missing parts, those in the wrong sockets, and
those that did not verify was corrected.
I got alternating messages of no
cartridge and a blank screen.
Slide the test sw on and restarted the game, the test screen came up
and showed no communication with the sound
Turns out, this was because I ran out of 128k eproms and wrote the
sound file to a
eprom. I realized I hadn't written the file correctly and re-wrote the
Here is what I got, almost there!
Pulling one of the Slag chips changed the color but removed the lines.
I removed the entire set of slag chips (4), keeping then in the order
A complete set of different slags was installed, pulled temporarily
a working Road Blasters cartridge.
The lines disappeared, and
restored the color.
Replacing that chip I had originally pulled (2nd) was the fix.
Here is the current screen output.
Below all missing, incorrect placed, or corrupted parts replaced.
Here is the working board as it stands
A total of 18 eproms were installed, plus the rest of the
parts missing, detailed before.
The remaining empty sockets, normal for this cartridge. The board was
designed to hold 128K or 256K eproms.
To put together the complete kit
to run this game, I need the CP completely populated with overlay and
I found someone that has taken on the task of making reproduction
control panels for system 1 games.
I was going to make the harness but another person has taken that one
as well and does a good job making it.
That left the overlay, marquee , buttons and the big one the Atari Logo
Reproductions of the art is on order. That was easy, but.....that stick
is a tough one. Not as difficult to find as a Pack Rat Stick but not
I found one, turned out though dirty to be in great shape, just
needed a little tlc.
It was obviously transferred to another game from it's Atari Life, as
the wiring was soldered to it.
As a matter of fact removing the wiring and solder from the leaf
switches probably took more time than anything else on reviving this.
All the solder needed to be completely gone so the new harness
connectors could easily slide onto the leaf switches.
Here the Logo ball is polished
Here completely cleaned, re-assembled with the new harness and (new
style micro sw_for now) buttons
The leaf switches were cleaned, adjusted and the stick lubricated with
It's ready to go!
BTW the manual instructs that the stick should be lubricated every 3
months on location.
Did this ever happen, at any arcade?, I seriously doubt it.
The final piece to complete the panel is the panel itself.
Thanks for this goes to Ryan (Vegas12 on Klov) .
These panels are very high quality, photos are included below.
Tell Ryan I sent you if your looking for one.
Here covered in new overlay.
Here is the bottom side with "new" Leaf Sw push button Assy's as it
Final Assembly, buttons, wiring harness and restored stick come
Not sure these looked this good when they came from Atari.
Here is a little trick I used to make swapping out the "cartridges" for
this cabinet easy.
Originally cartridges installed in the System 1 cabinet are
plugged into the main board and then secured with 4- 6-32 3/4" screws
in the corners.
Removing the cartridge requires you to reach into the far reaches of
the cabinet to get at 2 of the screws.
I changed that, with this.
These make pulling the board out and securing it a breeze. They
are brass with a shoulder.
They need to be this length as the connectors on the main board require
the cartridge to be mounted higher.
