I’m planning to pick up a JP in about a month. I’ll have only a few minutes to look it over and test it before buying it. What should I quickly check for before purchase?

Left/right/down/up on trex

scoop and trex saucer wear

Cracked ramp

Some JP came also with black grid, a member of this forum is in this case,

Sega bought the compagny Data East in 1994 wich correspond to the date of the end of production of the pinball. The only thing i know, is that the person who sold it to me, is the first owner of this machine, and he told me that he never modded his machine.

I need to check the serial number.. but if i remember right, this is a "end production machine"

If you don't have much time, this video shows quickly most of classic problems with the JP.. other things to check, burned electronics in the front panel and under the playfield (mostly the power supply is likely to have problems), rubbers, broken plastic playfield, and mostly, the decoration, check that everything is here because peaces are hard to find. The mosquito amber, the 2 pteranodons... (you can help yourself with good quality pictures from internet so you wont forget anything) also there are colored rubber cover for some bulbs most of the time missing (Top of the ramp Door, control room ect...) mylar or no mylar, but a lot of mylar is scary as hell. To finish, do a dianostic mode checking the switch/lights/T-Rex.. And the shaker, make sure it is working. A new shaker is 150 euros
All of this, estimated right can help you to get down the price. Trex not working could be a 200 euros motor broken, or decoration missing can get expensive, 50 euros for the two pteranodons that were missing on mine. Amber mosquito almost impossible to find! and very pricy.

Now you have to find someone next to you who owns a JP and exerce yourself to do all of this in a few minutes

Here a link of the video, good luck with your JP

Thanks for the video. I really liked the part where you mentioned they could be found for about $1200....how things have changed in a decade!

Avec plaisir
Yeah I wish I bought my appartment 10 years ago.. It is the only reason i waited so long to buy it
By the way, I forgot to mension about the Topper, It is a 100 euros more item if you want your JP to be complete. But no worries, there are very good reproductions on the market.

I made my own topper with papo dinos:

Poor Velociraptor, it has no chance against two T-Rex

That wallpaper border brings back some memories of my old basement. It does not come off easily.

Neal_W - thank you sir.

It was like that when I moved in. I keep meaning to take it down and re-paint...but a jam-packed gameroom has slowed my desire to do so.

Wondering if someone might be able to help me out. My T-Rex is missing the black skirt between it and the play field. I plan on making one out of rubber material. Can someone trace it out for me and email it to me please. PM me if you can help out and I will send you my email address.

Thank You,
Pete

Some where in this thread, some one made a template to cut it out. I wish the OP would star all the good useful posts in this thread and index them.

here is a post about the rubber t rex piece, I hope this helps

Anyone can sign up to get the ability to make key posts. At one point, I read through this entire thread, all 7,000 posts. I tried to key post the things that seemed important that weren’t already marked. I’ve marked the previous post as a key, so there are now 57 in the thread. Hope it helps someone in the future.

Awesome, Thanks!!

Is the Apron not supposed to be symmetrical?

Thank You

No - it sticks out more on one side. I think if you're looking at the t-rex from the player's position, the longer part of the skirt goes to the right side.

Yet another question. Just got my JP delivered today. I have 2 legs that measure and 28 1/2 and 2 legs that measure 30 1/2. Taller legs in the back? Anyone want to measure there legs for me?

Thanks,
Pete

I'm thinking about getting the color dmd "led" and also installing the 6.0 ROM set.
As the display ROM is modified in the 6.0 will the color dmd work correctly?
Like if the 6.0 has images that were never accessed or not at all in the factory ROMs... and thus were possibly not "colorized" for the color displays?

ColorDMD works perfectly with 6.0 and it looks awesome you won’t regret it.

Before DMD, I would highly suggest a PinSound. It completely changes the game experience and makes it significantly better IMO.

I did NOT know this.

I just bought a Space Shuttle. The owner's club is 48 pages long and there are ZERO keyposts. I just start from the beginning and look at it with newb eyes (which in this case, I am). Sometimes, the really old stuff is no longer even viable. Links to plastics, playfields, etc.

Mine are 28.5. All four. I'd put the longer ones in the back. Obviously, it would be like having 2 inch leg levelers all the way out.

Right now I'm struggling to LED pins, next year color dmds. I'm broke these days.
I've heard the JP pinsound on the internet and it sounded good.
But I advised a friend to get pinsound for a couple pins and it was probably the sound files but it didn't help.
He was bummed as it was a pricey thing ontop of it.
He had Flipper Fidelity in one pin and pinball pro in the other.
I have another friend with pinsound on LOTR and it sounds better but It doesn't seem to me the sound files they are using follow the action / modes as precisely as the original pin music, but I don't care for the pin music Stern used being electronic either though.
There are also some tech issues their repair guy attributes to the pinsound, but I'm skeptical.
I'm pretty happy with Flipperfidelity in JP right now.
Maybe some day I'll do pinsound with the full kit, but that's pretty pricey for me currently.
I would also like to experience it in person on a JP before spending that much.
That being said, what I did see/hear with Pinsound and JP posted here seemed amazing.
Thanks for the recommendation, I will take it seriously.

I pulled the batteries while the machined was powered off. Is it difficult to set it back to Free Play?

Super easy, you have to go into the adjustments.

Adjustment 30 is Free Play

What this is talking about is the foam rubber in the bottom of the A scoop so that when you shoot that scoop, it doesn't bounce over the switch.

Got it, all set. Thank You

My next topic. Anyone make plastics for this PIN. I need 3 pieces that I found to have cracks in them. Anyone making them?

Thanks,
Pete

Go to ebay and search "jurassic park pinball plastic" and you'll find a few.

Yes, I have been on the quest for "legit official" dino speaker grills for 2 years now. I do not know if mine came from the factory like this, but just assumed it was from some previous repair or had something to do with mine being a reimport from Germany. Never really asked around as I felt my machine was the only one I'd seen in pictures or vids with plain black.

I too have been debating the sticker route or finding a mod like the ones pictured earlier, but the purist in me never reached out to the guy to ask if he could do the JP dinos lol.

FYI - Here are my notes on adjustment and some settings I sometimes use...

Pressing Black with the green button 'in' starts diagnostics.
Pressing Black with the green button 'out' starts Audits and Adjustments.
When in a menu, set the green in or out to go to next or previous menu item when black is pressed.
Some higher menu items are not shown unless you go backwards through the list, or 'extend list' is selected.
Start button is used to change the value, then hit next to save.

adjustment 49 attract music = off
adjustment 4 game awards = credit -> Extra ball -> special
adjustment 46 trex eat balls = yes
adjustment 6 limit extra balls 3 -> 0
adjustment 41 tournament => EXPO (resets audits)
adjustment 30 Free Play

If you like craft projects with the family, print out the photo to scale, cut out the dino shape for a little stencil, then remove and paint the metal screen using the sencil. (flip it over for the left side)

I am looking for a couple pieces of plastic for my JP. Wondering if someone might have them lying around.

Thanks For Looking,
Pete

You confirm my story thank you!

A high quality scan would be perfect, could you share that with us? easy with google drive

I have one set of Data East Jurassic Park decals which I ordered for a customer that requested it during one of
our Group Buys. He later cancelled his request; but I forgot to remove it from my spreadsheet and ended up ordering it by mistake.
This set is a reproduction, new from Pinball.Center:
Precision Cut Decals, just peel and stick.
High Quality Print!
8 Decals
Ref. Part No.: 64986

This is the only set I have available; When it's gone... it's gone.
Will ship in stay flat envelope to protect the contents.

My wife has a cricut...had been debating going that route but never actually sat down to go find the image and match the colors lol

Well you got my attention! I have a friend who is going to make a high quality scan of his JP Grids to me, and i am not too bad at photoshop, mabe we could work together to make a vinyl cut with your cricut? i can make the files and send them to you, (would pay for post and Vinyl of course) what do you think? Send me a pm if you are interested

Finally was able to join the club a few days ago after picking up my JP Machine! I was lucky enough to jump on one that was in a family basement for just over 20years. I went through the audit tables and found it had around 1700 total balls played and not one System Failure. Hoping to be the one to eventually make it!

Playfield is immaculate, and everything else seems to be in great working order, just needs a little cleaning. Also, can't wait to brighten it up with some LEDs!

Only issue I'm currently having is sometimes the T-Rex will pick up the ball, but not swallow it. It just hangs out in his mouth while the game tries to find it. Pretty frustrating, but I've only had it for 48hrs so far.

Welcome to Jurassic Park... 60 million years in the making, enjoy

So I've been working alot on the machine lately, cleaning and fixing minor issues and came across this bungee in the middle of cabinet base. One end is connected to the cabinet but the other end is loose. Any idea what this is used for?

Maybe it's a thing on all machines, but this being my first one makes me wonder a bit.

Whoops, learning my lesson about searching these threads. Thank you.

Most all of us had to go through that phase.

Hi all. Did something dumb while trying to fix my power supply. I had to clip my black wires going to CN2 and forgot to label them. I think I have it right but before I turn it on does it matter which black wires you have going to pins 6 and 3? Can they go either way? Anyway to 100% tell which one goes to which if it does? Thanks.
