There's probably only a handful of people that could score that much on slow speed My highest on slow is 116K. Not sure about turbo, as I don't have access to a working one (a place not far from me has one, but the prizes are screwed up. They bounce outside the maze and award really oddball points, giving you letters in your score occasionally)
I can do about 70K at the most but I don't have a Jr. speed chip. I wish it was the same as the Pac/Ms. Pac one. If I had a dedicated cabinet, I would probably get the chip.
Yeah, Jr definitely takes patience, especially on the slow speed chip. That's part of my problem, I start to rush things and end up getting trapped My current goal is to clear board 7 (on slow speed). I've been there 3 or 4 times (including getting there on my 2nd man) but still haven't cleared it.
I'd like to play it with the speed chip. On normal play, I can get to the level with the locomotive treat. Maybe one after that, I cannot remember.
I'd like to see pics of your machine. Maybe I missed it, but is it a dedicated cab? I've got one, a real nice one. Sadly, its wrapped up in storage. But it was in my house for a good long while, and I played the shit out of it.
