Jungle Lord.

I have a working project that I picked up that didn't work 100%, but could be played.

Corrosion was significant, so I picked up a rottendog MPU/driver to save time. Gameplay still was not 100%.

It turned out there were power issues too, so I picked up a power board too (can't remember if it's rottendog or other, I think other).

That got it the machine up to 95%, but there were bugs in the game play, it would sometimes lose track of drop targets and the countdown timer to reset them.

Then one day it went completely down, no displays, no gameplay.

I'm in the process of restoring the original MPU and driver boards now. I have displays back and diagnostic codes, just not back playable yet. I think actually that I might just need to put in new roms and I'll be fine now, the boards were sitting on a table for a a month or so before I realized they got full sun during part of the day - ie would have wiped the eproms. I haven't gotten to installing them yet - hoping that when I do I'll be back to 100%.

Only one? That would be cool. Hope I can get there someday.

STTNG.....It got to the point where I was afraid to turn it on when guests were over, because something else might go wrong. Great gameplay, but wasn't worth the hassle for me.

I've never had one game that kept me busy more than others, but I do have one mech that I hate. The damn auto launch is the bane of my existence. I've never gotten one to fire a ball correct 100% of the time.

That and the trough kickout. Somehow I end up with games that will kick out a ball, it will bounce off the rail and go right back into the trough. I still can't get that tweaked out 100%.

Obviously no one here owns a Black Knight.

My first love and machine...Firepower. I have restored this thing from the ground up and it still isn't working right. Sure is a beautiful machine now...man I'd love to play it!!!

Sttng for me! I have had mine for 12 years now and i still have this opto issue that i cannot find the solution for.

Doctor Who for me. I can never get my MPF to stay aligned properly.

I haven't owned that many in my time in this hobby, but Johnny Mnemonic is definitely the one with the most problems. Totally rebuilt the hand and it still never worked right. Seemed like it was always something with that pin. Happy to see it leave.

Great I've committed to buying ST TNG which so far looks to be in great shape and now everyone says it's hard to keep going? It is going to be looked at by a tech but I'm a little concerned.

My JM is the same as yours. Unfortunately I enjoy the 95% game play too much to even think selling. The hand is the pita! Main issue is it always picks up two balls. I have bent the whole mechanism gently upward toward the sky, I have replaced x & y nuts, new magnet and hand switch....still nogo. I think the pin laughs at me behind my back....no wait! It laughs at me in front of my back and while I'm playing! UGH!

After owning two of them, Black Hole is a PITA. Still a cool game however. I agree the mist ball on BSD can also be tricky, but that pin is fun and challenging regardless. If any pin works 100% for more than 6 months, the owner probably prays regularly and is blessed by God himself.

Yeah, I'm not saying it wasn't a fun game. It was a blast to play, probably the fastest game I have ever played. Just got sick of constantly f..ing with the hand.

I was looking at my '94 notes. My tech, who maintained a very large route, told me to avoid SS, IJ, STTNG, and we sold TZ and FH because of problems we couldn't reasonably fix. Things have obviously changed. For example, the replacement metal arc above the scoop in my AFM can't be bent back like the original.

In my collection, black hole is the one keeping me busy "under the hood"

Mine from order from most work to least work...

Jurassic Park (#2) - New DMD, New DMD Driver Board, New CPU, New Coils, Re-Soldering, etc., etc., etc.
Johnny Mnemonic - Had intermittent hand issues. Final fix seemed to be re-soldering the board.
Jurassic Park (#1) - Minor tweaks here and there, but overall a solid machine.
Pin*Bot - No issues so far, but I've owned it for less then a year.
Fish Tales - This thing was rock solid. Owned it for five years and it always fired up like a champ.

My Space Shuttle is a constant battle.

No one has mentioned Addams Family!
Always something, just when you get the bookcase right, the swamp will curse you, then its a flipper, a target, that darn ramp, now sling shots have been acting up. Curse of the Addams!

Champion Pub.....Speed bag assy blows switchmatrix IC's at CPU board and more.......heavy bag assy wiring breaks, and breaks and breaks and..... Arms from boxer breaks and breaks again.....then the rope starts turning again and never stops....., gearbox rope motor starts leaking oil....opto nearby doesn't like that..... Nice game but a ***** to maintain......

Gottlieb System 80 is always scary. I got rid of Black Hole because I had a feeling it was just going to fry one day. Never knew what it was going to do when I switched it on. All the boards were grounded (bullet proofed) and in excellent condition. But it still acted wonky all the time and theres not really any useful diagnostics.
