I finally got a pin...RESTORED AND LOVING IT.
ChadTower:
Some helpful stuff.

$80 replacement board
menace:
I recently refurbed a gottlieb sys80b--replaced the power supply in the backbox with one from an arcade machine (long live peter chou) got a solid +5 out of that as opposed to from gottliebs shaky pot (not sure if system 1's have the same setup)
When it came to edge connectors I said "screw you crimper" and bought a bag of .56 molex pins and solder the wires into them--100% solid connection and without a decent crimper the connection is waaaaaayy better (i personally found it faster but I'm a soldering demon and a crimping newb)
Another thing I had to do was replace half the fuses with the proper sized ones (might want to check that--lots of ops just up the fuse rating until it stops blowing).

Sys 1 needs all kinds of voltages. The CPU needs +5 and -12. The displays need 64 and 42 I believe. A pc power supply is recommended for a test bench setup. I don't think it is a viable long term use inside the pin though.

BTW, I am slowly building up an order with mouser. So far, I have the stuff to redo the connector pins, the stuff I need to rebuild the power supply (for $10 or so, it is worth a shot), about 20 1n4004 diodes for coils, 2 switch diodes (40 cents a pop, so just 2). I also need to order some matching fuses to keep on hand.
My question is, are there certain things I should go ahead and get "because I'll need them sooner than later" from mouser? Specific cheap transistors that are common, or anything else you may think of recommending.

Maybe a look at the driver/main board and order a couple of whatever popular transistors are on there. Mine were u45's and a13's. I had to order 10 replacement u45's for the aux lamp board and at least 2 a13's were bad for a couple of playfield lights.
Again there are big differences between sys 1 and 80b but you can check your transistors with power off and the board pulled in any case--you should be able to tell if you have some that are bad or questionable.
Another part I had to scrounge were silicon germanium diodes (clear glass looking things) needed about 4 of those but they were for chasing lights so if your game doesn't have them its a moot point.
If you are doing any chip replacement make sure to get a chip socket installed--makes any future repairs easier (not worth installing if things are fine though).
I'm sure there's more but can't recall right now...
