Star Trip cocktail pinball - *sold*
RayB:
Now I have to figure out why this MPU-2 has jumpering on the back that does NOT match any mod descriptions on http://www.pinrepair.com/gp/ (the front mods match the 2716 mod, but the back does not).
Since it's a long-shot finding anyone who knows much about this (unless Echo Lake or Flippers are kind enough to offer free advice??) what's the concensus here on what I should do? A pic of this extra jumpering is shown below. I'm thinking I will cut all the jumpering that does not match the instructions on PinRepair.com, and leave all mods that make it 2716 compatible. Does this sound like the right choice to you guys?
ChadTower:
Depends on what the chips are that are being jumpered. Can't see that from this side.
RayB:
These are the ones involved (bottom)
# U5 - 74LS32
# U6 - CMOS RAM HM6551-9
# U7 - CMOS RAM HM6551-9
I think I've figured it out. This board had the "Converting the 6551 RAMs to 5101 RAMs" mod done to it, and those small jumper wires "reverse" the mod.
The long jumper wire (top of my pic) is another mod related to using 2732 eproms, but it connects to a 'dead end' so it's as good as not being there at all.
I guess the board is good to go once I get the new ROM chips.
Thanks for looking.

Funny....that was my first pin too, though i never consider it so since i only had it for a few days...actually it was a Gameplan Star Trip converted (beleive it or not) to an 8 ball deluxe. Wasn;t exactly a good first attempt at pins.
I got it for free, posted a question about it and was offered 400, I saw it soon after for 1000 on ebay from Todd i think, in PA. I guess he brought it out to a show and had lot of interest in it.
It's pretty cool but a monster hog of space.
