I finally got on the HS board on my Taxi...and my initials wont enter?? Everything on the game works flawlessly save for this. The start button will still toggle to the next initial, but the flippers do nothing? Any suggestions???
 
Never worked on a Taxi, but I know on my Swords of Fury (sys11 also) there is a bladetype microswitch actuator that sits on the leaf switch. When you press the flipper button it activates the leaf switch for the flipper as well as the microswitch for entering high scores.
 
Do your cabinet flipper buttons allow you to change the rollover lane lights? That's usually associated with the same switch contact??

No, they don't. Its funny, I played Taxi on the WHOF XBOX360 game, and noticed you could change the lit lanes. I figured they did that to add something new to the game since my actual Taxi didn't do it. Its supposed to, huh?
 
If I remember correctly it should change the lit lanes Jow. Most games do that. I don't have any experience on that system, but the link tom posted should have what you are looking for somewhere in there.

Taxi does have the lane change feature.

Also note that Taxi does not have the additional switch contacts as mentioned above. Taxi used an opto-isolator to feed the flipper switch circuits into the switch matrix. I recall that the opto-isolator is on the interconnect board.

My money would be on a bad opto-isolator.

Lane Change on games with Interconnect boards.
When the interconnect board was introduced on Banzai Run, Williams stopped using a doubled up switch on the flipper EOS switches for the lane change. Instead, circuitry was added on the interconnect board using a MOC3010 opto coupler. If you have problems with the lane change on these games, replacing the small 8 pin MOC3010 opto couplers will usually fix the problem.

I would probably test it before replacing it personally but the part shouldn't be more than a couple bucks.
 
Can anyone tell me where that would be? Sorry, I cant open the link at work.
 
I wish I could help you Jow. I am just sick over this. Beside myself frankly. Color me helpless.

Thank you for the concern, Phetishboy. If I know my fellow KLOVians the way I think I do, the help will be here in no time flat. I will post pics of my initials on the HS table as soon as this is all hashed out! Color me tickled!

I was all for helping you but now I would just like to fade back into the shadows. You scare me.

The interconnect board will be the long board in the bottom of the backbox. It's the one with the cement resistors and fuses mounted all over it.

The MOC3010 is on that board, it's a small 6 pin IC, should have MOC3010 printed right on it.

The part is still readily available (Jameco for example), can be had for under $1

Awesome, thanks for the info my man.
 
Jow this is a part Radio Shack carries.
Their part # is 276-0134 (possibly 276-134)
If there's anything I;ve learned from buying from the ratshack is to call ahead and verify they physically have it on hand. If they say "the system shows it in stock" tell them you hate computers and don't trust them.

Dude, sweet. There is a RS right around the corner from work. I'll check it out. Thanks bro.
 
Your Taxi Interconnect Board may not have the Opto Isolators on it (according to the Parts list - on page 40 and schematics - Page 79 which shows none on that board). I have a Taxi Project which I bought which was missing all of the boards and displays. In trying to get it up and running, I bought an Interconnect board (D-12313-2014 - Pool Sharks) off of EPay after reading info on Clay's site and comparing the schematics. The Taxi Interconnect board (D-12185-553) did not have the Opto Isolators on it, but the Pool Sharks (U1-U3) did. Maybe the Manual is is wrong (Not the first time I found issues). If they are not there, I would probably check the circuit that contains Q46 (1J8-9, 1J10-8 and 1J10-9 wires) - which handles the right and left lane change switches.

I will have to check when I get home from work, to see if the lane changes and High scores work on my basket case machine without the Opto Isolators

Interesting. This post got my curiosity, so I went back into my own Taxi repair logs. I do have notes about the opto-coupler for Taxi being a failure item. Interestingly enough doing a quick search on the RGP newsgroup shows numerous posts with some discussing opto's and some talking about microswitches. I am beginning to wonder if there wasn't some interim design change (we know there was an artwork change during the run, how about some hardware)? I'm curious what you and Jow actually find for a setup.


To Jow, if your board does NOT have the opto, the lane change setup used prior to opto's were microswitches mounted on the inside of the cabinet near the flipper buttons. The microswitches had an unusual looking arm on them that went up against the back of the leaf switch for the flippers and was actuated when the flipper button was depressed. So, if no opto, look for the additional microswitches inside the cabinet.

Please let us know how yours is setup, I am very curious.
 
When looking for information on the interconnect board and all the other boards, I also did searches on RGP newsgroup and saw numerous posts with some discussing opto's and the microswitches. In the image on IPDB of the back box boards, it seems like the Interconnect board did not have the Optos. I kind of figured that there were different variations out there, either from the factory or being on route.

I think that everything is working correctly on mine (Lamp, Display and Switch tests seem to work on mine), but I am using alot of different boards - none from a Taxi. The power supply, main display are out of a Whirlwind - The interconnect and Aux Power are out of a Pool Sharks, MPU and small display from a High Speed, and the sound is out of a System 11C game. I just wanted to get all of the boards working on mine, before proceeding in doing a complete restoration (Have had it since February). None of the boards I have bought off of EPay or Mr. Pinball were working, so I have invested alot of time repairing/troubleshooting problems on them.

I will have to check the flipper switches when I get home. I am really interested in what I will find. Who knows, this thread may have fixed another problem which I did not know I had. Thanks for all the information.

Just checked and my Taxi project does have micro-switches, hence there is no opto's needed on the interconnect board. The lane change and High score initials do work on mine. Hope this information helps.

Deadly - this part # didn't come up on RS website?
