I just put an NVRAM in our machine. Love it. My wife is a better pinball player than I am, she destroyed the Ring in 36 seconds, but then the batteries gave out. That was sad. She was urine'd off to say the least
When we went back in and re-worked the settings we left extended attract mode on. I have read that this can stress the game, and not to use it if it's a location machine.
Anyway, last night I had it on and I noticed that the display was just going blank. And the only light blinking was the Barad-dur light (which is part of the extended attract mode display). So I turned the game off, turned it back on and it did the same thing. So then, went into settings, set that to OFF and it still did it. Turned the game off, turned it back on this morning and it hasn't done it since.
Extended attract mode in this game goes through the lore poem, and uses various parts of the playfield as it does it. It's cool, but I wouldn't leave it on. For good measure, this morning, I reset the cable for the display.
But anyway, I have only added a four ghost Army of the Dead platform above the POTD. It looks really cool. That's the only mod. Game ROM's are 9, as I bought it. It is remarkably clean and in remarkably good shape, almost like new, but I may be somewhat subjective. Only issue I have ever had with it is the right VUK. It gets quirky and will not eject the ball from time to time. And just in the last two weeks, I had to replace the pop-bumper flasher transistor on the board, as those flashers were not working anymore. It took me longer to take the board off, and put it back in the box than it did to remove the old one and solder the new back on LOL.
I am the second owner of this game, bought it in early 2007 from the original owner who had to sell it because of space consideration. It's a great game, and I recommend it to anybody that has the money to find, and then purchase, it.
oh btw, no LED's yet. Not sure if I want to go there, and it's my wife's call. It's her game, I just work on it
