Quoted from daley:The displays are too low for me.
I cut vertical slots in my display board PCB, in order to allow alignment.

Quoted from toyotaboy:So off to the scanner to get a starting point, trace over it, and get a clean image to recreate my own in 1/16" PETG.
New plastic is on top, old is on the bottom:
Note: from factory red flipper rubber wrapped on bottom posts.
------ Metal bracket fits under D/T plastic.

@LimeWad. I used a Gottlieb wide "L" bracket that they used to secure ramp entrances.
Gottlieb part #21158.

Quoted from ravve:I dissabled the plastic ramp and some other things, but forget to note where this piece goes.
Anyone?[quoted image]
Top left curve of ramp.

Quoted from mcalon:Another thing that had me thinking is that the manual shows microswitches with some levers as flipper buttons actuator, my machine has normal leaf switches. Also the flippers coils are different than what's written in the manuals. My coils are 5020-30 while manuals say 5020-20.
I am certain that no one replaced coils or switch mechanism. I wonder if anyone else has this conflict and what's the story behind it.
pg.26 Flipper coils are 23-900
pg.55 info is brought over from first game to use S.S.F.B. unedited.
pg.29 playfield parts list flipper item #49/#50 as 500-5177-32/500-5177-31.
Note:
500-5177-31 } 23-900 coil 090-5020-30
500-5177-32 } Solid State No End-Of-Stroke switch
Quoted from ElCid95:type of screw
Data East used #6-32 Mach.Thread. or #6 Wood Screw.. depends on application.
Fasteners can have hex head with #6-32 tread on top side.
Sega Manuals list variety of custom fasteners... like 530-5012-02 or 530-5010-02.

Quoted from mcalon:Thank you
Do you happen to know what's the story behind leaf switches installed instead of micro switches?
Phantom had micro switches... Sometimes the cabinet micro switches would fail...
Heavy adjusting and bending the actuators made things worse.
A good quality heavy duty micro switch assembly should work fine, if all the connectors
are clean and have a good connection to the driver board.
The leaf switch style with round gold flash contacts workes good too...
But, the contact points would beak off sometimes...the worst are the new style that
Stern has. The tiny spot contacts again, come come off the blade.
D.C. Tungsten contact do not work well with the +5 volt circuitry of the solid state flippers.

Quoted from DakotaMike:Bump. Anyone?
Rom code is country dependent. USA lists has A02-0 B5/C5
Some version are language/coin price default.
BTTF has one big bug. The condition fries the green brights/flashers under the ramp.

Quoted from defonze88:Thanks, I got the 90-5020-20 like you said and hit way too hard. I appreciate the response
Corrected part for flipper coils is 090-5020-30, 23-900 coil.
Here's an old photo from a really clean BTTF pinball.
