Hi Guys,

Joining the club in a few days. Super stoked. I am basically getting this one based on seeing 2 pictures so unsure what I am in for but from what I have seen she looks to be stock and in good condition, topper etc. But missing pterodactyls.

Any reccomendations on upgrades? Rom, LEDs? ColorDMD?

Any typical faults to look for? Problems that should be fixed? Does the Trex use the same motor as Twister?

I am hoping there isn't a crack in the unobtainium plastic ramp but if there is, any advice on repair methods?

Also wondering if anyone still sells those newer JP Gates that mount over the ramp?

Anyway any advice appreciated and I will start reading the forum and see what I can learn.

Cheers

1) ChadH roms are a must.

2) I run Comet led's and flashers myself, a fire led behind fire on backglass.

3) Color would be good choice for this title, don't run one myself though I just did pickup one for Star Wars.

4) Motor is unique but available, not same that I'm aware of.

5) New ramp available from Pinballlife.com

I added a Jeep, foliage and a few raptors to mine and lit the "dinos ruled the earth" plastic.

I chose to keep incandescent bulbs on the top-site as I prefer the warmer old-school look, but used warm-white Comets under the all inserts and in the backbox. Game feels bright and refreshed! The under-ramp flashers are amazingly bright, I love it! Also added an LED strip behind the dinosaurs banner, like shown above. Of course added Chad's ROM and an NVRam to replace the batteries. Kept the original DMD.

My JP is perfectly tweaked to my preferences!

Enjoy yours.

1) I like using the retro led bulbs, clear dome with warm white to mimic incandescent.

2) Yes, NVRAM over batteries. I like NVRAM so much and so easy on Data East I buy the stuff in lots of 10. Its almost mod #1 when they come in the door.

Quoted from Inferno:

Howdy, I have an extra NIB Tim's Gate Mod that I would like to sell. Tim came out of hiding last year during the lock down so I bought 2 from him. I installed one, and the other is just collecting dust on my shelf, so I thought I'd put it into circulation. DM me if interested. $300 shipped USA.

I love my Tim's opening gate mod!
Hope for the other owners he starts making them again!
Real great mod

Thanks for the advice. You have a great looking JP there! Glad to hear the ramp is also available. It's the major concern I have until I see what I'm getting. Recently refurbed a Twister but couldn't replace the broken ramp. I will definently get the updated ChadH rom. I have his rom in my TFTC and it was a huge improvement in game play. I do like the idea of adding a few additional things to the playfield.

Yeah I hope so too. Only just started reading up on it. Looks really good and suits the game perfectly.

I don't have Facebook, do you know if he has an email address? Would like to register interest in case there is another run.

Nice one. I was 50 50 on the decision to put LED's into my Tales from the Crypt. The older incandescents gave it a perfect retro feel that felt fitting the theme, even the classic speaker hum seemed right. I might put them back in one day. Data East's do seem to be very flashy and bright when fully kitted with LEDs. I imagine JP will be flashy too! In a good way.

Do you know if you went with warm white or cool white for the banner LED strip? Probably wouldn't matter either way? Does that strip mount on the back wall of the cab?

I think only one color white is available in the right size, I made a bracket.

Sorry, don't recall exactly; guessing "warm". It does not feel "cool" to me at all, which I dislike w a passion. I added a Comet trimmer in-line to allow me the ability to tone down the brightness to my liking.

All good! Was just curious. Cool White, think more bright white dentist light. Where as warm white has more of a traditional yellowish, light bulb feel. As long as it lights then it doesn't matter either way really!

Use 20" Comet Matrix strip light "sunlight" color, clear, with dimmer which I didn't need. Gives the look of outdoors, which is perfect backdrop lighting to the playfield scenery. Made a simple aluminum strip stock bracket for mounting it. Changes the whole feel of the game and brings it alive.

Started rebuilding my flippers and ran into an issue. First time doing this on a data east and the replacement ones looked a little different to the old ones.

I got this kit (link below) quite some time ago so it had been sitting in a box ready to go (both left and right).

https://www.rtbb.com.au/product/data-east-flipper-rebuild-kit-04-1993-to-06-1994-and-early-sega-1995-right/

I cant seem to figure out where the spring should attach.

I would have expected there was a longer spring bracket arm protruding from the flipper paw like this set : https://www.rtbb.com.au/product/data-east-flipper-rebuild-kit-06-1992-to-04-1993/).

DE0692-0493_resize (resized).jpg

Anyone have a picture of that first style kit installed so I can see where the spring is supposed to go?
or is the page wrong in that it says it worked on a jp when it doesn't?

edit: tried using the old spring bracket (545-6422-00) but the rear plastic can no longer be screwed on so switch is never touched.
I also noticed that marco's says it can be used on a JP ( https://www.marcospecialties.com/pinball-parts/515-5051-00 ) yet pinballlife says its only the ones with the additional spring bracket ( https://www.pinballlife.com/mm5/merchant.mvc?Screen=PROD&Product_Code=PBL-100-0097-00 vs https://www.pinballlife.com/data-east-and-early-sega-plunger-and-crank-assembly.html ).

ah sorry, i just saw that you posted that the bolt is too short then. Longer socket head bolt from the hardware store possibly?

#8771 48 days ago

you can always opt out of the extension style spring used on the side and use a compression style on the plunger like how the DE Playboy used.

I will be shipping my DEJP on a 600-mile journey next month. Are there any devices or parts unique to this game that should be secured, protected or removed to minimize damage (besides the obvious?) It will be blanket and plastic wrapped, no pallet. Insured. Of my 6 machines, this one worries me the most.

I know the T-Rex. was mounted in the down position with a foam block to help keep the figure from bouncing around.

#8775 47 days ago

I believe I've seen that. Will do. Good safety precaution. I'm also planning to remove the toy mods which were fastened for stability in a horizontal machine. Gravity in the upright "bouncing" position changes everything.

#8776 47 days ago

Hi all, just joined the JP Owner's Club this past weekend! I'm absolutely stoked; been dreaming of owning one of these machines since I was 10 years old! Still in a slight state of disbelief. Bought the one posted for sale in the marketplace from "stealyourface," was such a pleasant transaction and he was a super cool guy.
First impression when I went to pick it up was "Man, this machine is TALL. Will it even fit in my basement??!" Thankfully I shortened the lengths on the leg bolts by a couple inches before setup, and it fits, with maybe a couple inches worth of clearance between the head and my floorboards.
Love the game; been playing it so much since I got it home. One question for the rest of you, though- is it always so "jumpy"? Feels like I'm getting airborne balls left and right and don't want to destroy the playfield if I can avoid it. Wondering if it's an issue with my setup/levelling, or if it's related to flipper strength, or something else...?
At any rate here's a pic of her all set up next to my Paragon, which now feels absolutely dwarfish in comparison:

The topper is fragile compared to the rest of the machine, but can be removed with 4 phillips head screws.

Not really sure, I can't say mine doesn't airball but it is very rare.

I was getting a ton of airballs after installing new Titan rubbers on my machine about a year ago, but I think this was more related to my flippers being off, which was sending the ball a little too hot.

I've since done a full flipper rebuild (highly recommended), and don't see as many airballs now. I still get a few, especially when I miss the ramp shot, but nothing like a saw a year ago.

Congrats! I too joined the club this weekend. Any idea what type LEDs are used in your game? I need to upgrade mine.

I also need to get some help as game had issue last night and stopped working...I'm still a newbie when it comes to diagnosing problems and fixing things but I want to learn.

#8781 47 days ago

Hi all,

Joined the club this past weekend and game was working just fine until last night. My son was playing and he said the the game said multi-ball initiated and then the machine just seemed to go dead.

The GI lights turn on but that's it....the color DMD doesn't turn on, there is not sound and the game doesn't boot and initialize the mechanics (probably saying that wrong)...

I'm a newbie when it comes to diagnosing and fixing issues. I am eager to learn and don't want to have to rely on calling a tech out if there is an issue.

I checked and changed the batteries...there was no corrosion or acid....I will be upgrading to NVRAM (any suggestions of where to purchase?)

I checked all the fuses (I believe) and didn't see any issues there.

Did my power board go out?

I cant even get into diagnostics mode.

I'm not sure what steps to take next --- any advise or suggestions is much appreciated.

Thanks in advance for any help.

Go to pinwiki and read up on how to check your power supply voltages. It sounds like you lost your 6 volts.

#8784 47 days ago

Picked up my JP today and so it begins! Feel like I am a bit behind on the mods side of things as alot appear to be sold out - would sure like a set of those gates!

Looking on the basic upgrades, has anyone used an LED kit on there JP? Any advice/reccomendations welcomed. My last kit was a cheap set for a Twister. Massive ghosting on that game but was able to install an LED OCD board to fix and smooth it out. Anyone had similar issues with JP?

I read there are 30 flashers in JP. I know Data East's are known for being flasher heavy, but the 90s incandescents didn't pack alot of punch. Do that many LED flashers make it blinding?

Thanks

#8785 47 days ago

Data East CPU boards have the +5V and ground test points located just above the battery holder's upper right corner and to the left of connection CN17. Connections can be made to the appropriate pins on CN17, but it is much easier just to use the test points. Hopefully, you have the schematics and parts drawings to help.

Look closely at CN8 and other connectors to make sure there's no evidence of burning.

Hi all,

Joined the club just a few days after a spare Tim's gate mod sold here a week or so ago. Definetly would have jumped on that one! So I just wanted to ask if anyone has any JP mods there thinking of selling I am interested and would appreciate a chance to buy.

Still reading up and learning on all the great mods over the years but from what I can gather the upgraded T-Rex and Gate are unibtanium. Can't seem to find any scoop signs in stock. Wondering if the white ball for the raptor egg is a Powerball? Or variant? And looks like there was a raptor cage at one point?

Anyway any advice appreciate and happing pinballing!

The Jeep makes a great mod, usually on Ebay for $20 or so.

Hi...I'm not getting any reading on the CPU test points...does that mean issue is with the power supply board?

#8792 45 days ago
Quoted from debooen:

Hi...I'm not getting any reading on the CPU test points...does that mean issue is with the power supply board?

Maybe.

The Power Supply Board (PSB) has test points on it for +12VDC [Volts DC], -12VDC, +5VDC and a Ground. These are up at the top of the board to the right of the big silver heat sink and to the left of the yellow and white wire bundle coming off the board.

1) Turn on the machine and check here for +5VDC. The black lead from the multi-meter can go to the ground test point and the red one to the +5 test point.

If present, the +5VDC section of the PSB is probably ok.

If you do not get +5VDC, turn off the machine and remove connector CN6 (Power supply board to MPU board, bottom left hand side of the PSB), turn on and test again. If you get voltage now, something is using up all the voltage before the MPU board can use it. This could be the cable, corrosion or a failed component, but it means the problem is probably not the PSB.

+5VDC is fed to the DMD Display via CN5. The pins for this connector also carry higher voltages, be careful when the machine is turned on. Turn off the machine, remove the CN5 connector (next to CN6), turn on and test for +5VDC again.

If you get +5VDC after you disconnect CN6, the DMD parts of the machine may be sucking all the +5VDC out of the system. Not likely, but they need to be eliminated. You could reconnect CN5 to the MPU and check again to verify it is just the DMD.

If you don't get +5VDC, move to the +12VDC test point on the Power Supply Board and test there. CN5 and CN6 are probably not involved; you can reconnect them if you want. You can use the same test point for the ground side as you did with the prior test.

The Power Supply board makes 12VDC from the Bridge Rectifier, then uses 12VDC to make 5VDC. If there is no 12VDC, the board won't create any +5VDC either even if that part of the circuit is ok.

If you get +12VDC but not +5VDC it narrows it down to one area of the PSB, if you don't have +12VDC, it's another. This isn't a solution to your problem, but it'll get you closer to one. Post your results.

Edit: I just reread this and have a typo in the DMD notes in one place. DMD connected to CN5, not CN6.

Should read "If you get +5VDC after you disconnect CN5, the DMD parts of the machine may be sucking all the +5VDC out of the system. ..."

My JP is still all incandescent, I'm thinking about changing the GI to LED to brighten it up but leave inserts incandescent.

Could I have some opinions and pictures of the GI choices of Sunlight vs Warm white?

I tried some sunlights on the slings and wasn't sure if I liked it versus the incandescent feel.
So thinking warm white might suit JP better?

Hi all,
Can't seem to find any scoop signs in stock. Wondering if the white ball for the raptor egg is a Powerball? Or variant? And looks like there was a raptor cage at one point?
Anyway any advice appreciate and happing pinballing!

Yes, the egg is a powerball.

I have an alternative to the scoop signs in my shop. More pics & info in the links at the end of this post. PM me here or reach out through my website.

Hi all,

If anybody has some photos on how/where the 2 Pyteranadons mounted to the playfield it would he appreciated. Mine are long gone. Sourcing some model replacements but will have to form-up some wire to install.

Thanks

Steve

Thanks Gord. Perfect! That will help me get it placed right.

Your JP looks to be in amazing condition. Not even any wear around the scoop. Nice.

Thanks for the kind words CryptKeeperAUS. I picked this JP up in June of 2015 from the original owner who had a really nice all original collection of 90's era DMD pins. The first thing I did for my JP was to install plastic protectors and also Mantis protectors for all the scoop holes.

Yep, good idea to keep the playfield looking good for the years to come. I have just ordered some of the plastic protectors for the Raptor Pit and and slingshots from up-kick pinball on the marketplace. Great guy and even covered the unexpected additional shipping cost. I had been using the smaller round clear washers on my other pins but looks much more professional with the cut to shape protectors.

Hi all, I'm just shopping my JP 93 and have replaced the screws retaining the plastics as they were all corroded after all those years. I wanted to get some nice new nuts for the plastic tops, what size are they please? I don't want to order the wrong ones and go to big/small.
