i was at a friend's birthday party saturday and was getting a beer from the cooler in the garage when i saw a familiar silhouette under a tarp in the corner. curiosity got the best of me and i lifted the tarp to see it was a pole position 2 cabinet. while i LOVED PP as a kid, i never added a PP cabinet to my collection because of their notorious dependability issues. i asked our host about it and he said it was his brother's and that he'd stored there about 10 years ago when he went into the military but never picked it back up. "it doesn't work, so he told me to get rid of it a couple years ago, but i've been too lazy... you want it?" he asked. "yes" i said without thinking. i mean, i couldn't beat it at that price, right?  Grin

so i went back and picked it up on sunday. here it is right off the truck... i haven't really had much time but to unload it and power it on, the monitor looks pretty good, nice and bright and i don't see too much of the usual "game over" burn-in i see on most of them. so, ANOTHER project to the pile!

Screen looks very similar to a troubleshooting image I was saw on JeffsGames.com:



Here's a link to his whole article:
http://www.jeffsgames.com/2008/05/28/pole-position-2-pcb-repair/

My PP2 PCB had chips missing everywhere and my only solution was to mail it off to Eldorado Games for repair. Notice the article mentions battery acid damage should be checked to see if any nearby components are in distress / messed up / etc.

I was email a guy about a Pole Position myself that sounded like it was in good shape and had a Ram 7 and 8 error. Being as I have a Ms. Pacman project going and a cocktail table going I thought I should probably stay away from this one until at least one of the 2 are done. Not to mention I have Final Lap already so there is limited space now for racing games. Looks like it's in good shape! Good luck too!

Have you tried to put it in test mode yet? Its possible the ram went bad on it, that's similar to what happens when the video ram dies.

I would start by putting qd terminals on all the power test points to get power off the due connector. John did a video about this on how to bullet proof your pole position. I would also make sure both AR2 power supplies are running at 5v and disable the voltage sense. After all that is done can you start worrying about the game board.

yeah, power supplies are testing good... looks like a board issue.  Undecided

oh well, it will be a good time to do the power modification too.

when you tested the power supplies were you testing them from the harness or from one of the game's testpoints?
Its pretty useless to test a power supply unless its under load. etherway, do the power 'mod' and disable vsense on both AR2s. once that is done can you start worrying about what is wrong with the game board.

my pole position II lives!

at first, i just thought i'd wait for adam's ppclone project to be done, but i finally had some time to spend poking around on the boards... luckily, all my edge connectors were in great shape. i replaced a socket on the CPU board that had corroded pins and cleaned up some acid damage from the battery and she fired up! cosmetically, i did some painting of the coin doors and pedal, cleaned and rebuilt the steering and shifter. i also replaced the cracked t-molding and added more "grippy" no-slip tape to the pedal. now, i just need to make another monitor shroud to replace the ripped/crushed one. i also plan on doing the "bullet proof" mod...... eventually.

all-in-all, very happy to now have a working pole position in my collection! a BIG thanks to all the folks here who gave me pointers when i needed 'em!
