Cabinet and Backbox: Most of the cabinet exterior has been repainted with a fresh coat of dark blue gloss paint. Some flaking off of the original paint was present in most of these areas on the backbox and main cabinet so we cleaned up and restored these areas with fresh paint. The game's original artwork on the cabinet and backbox sides has been retained and is in great shape showing only a few signs of past use and age- overall very nice looking.
All of the metal parts and black carriage bolts on the exterior of the game have also been removed, refinished, repainted, and reinstalled, to reflect an original, new "factory" look. Cabinet also includes new white nylon gliders installed on the back panel, new flipper buttons installed on the cabinet sides, a new backbox lock decal on the back of the game, and fully reconditioned and repainted coin door. A new chrome ball shooter housing and parts have been installed to restore "like new" action to the ball shooter.
All circuit boards inside the backbox have been inspected to ensure good healthy condition and reliable operation. Many parts have been replaced or upgraded for better, more reliable operation, including new parts on the power supply and several new connector plugs with heavy-duty connector pins for improved connection and reduced heat buildup. A new remote-mount battery holder with connector has been installed to replace the original board-mounted batteries for the MPU board (memory backup batteries). This not only provides reliable power to the memory when game is turned off, but prevents damage to the valuable circuit board should the batteries ever go neglected and burst/leak (common cause of circuit board damage and costly repairs in games that have batteries still on the PC board).
Both 16-digit score displays have been replaced with brand new units for longevity and added reliability. These once again have a great, brand-new, fresh look to them and are easy to read. ROM chips on the MPU board and sound board have been checked and upgraded to the latest revisions that include the latest bug-fixes and enhancements, where necessary. All fuses on all boards have been inspected to ensure proper types and values for proper operation and protection of the game's electronics.
Coin door on this game has also been restored completely- inside and out. Door was completely stripped-down into all individual parts. All parts were hand-cleaned, and metal parts were all prepped and painted in original factory semi-gloss black enamel, and entire door was reassembled and again appears just like brand new. Coin mechanisms are present in the game (U.S. quarter mechs) so game can be operated by coins, or "free play" if so desired. Coin door is complete with fully working wiring, switches, and coin mechanisms. A new lock and keys have been installed on the coin door as well.
This game features brand new leg bolts and levelers on the legs, as well as new leg protector pads. The new leg protector pads help to protect the cabinet finish against wear/tear from the metal legs- a nice finishing touch to this full overhaul.
Backglass on this game is original and in great condition showing very few signs of use or blemishes.
Here is a detailed list of work that has been done on this game, followed by more details on parts and game modifications:
We have invested just over 60 hours of work in the restoration of this game.
Playfield top and bottom surfaces stripped of parts and assemblies for proper cleaning and rebuilding- right down to the bare surfaces.
Playfield surface fully cleaned and polished.
All playfield parts & assemblies have been removed and hand cleaned, or replaced with brand new parts where necessary. This includes light bulbs, posts, wireform ball guides, flipper assemblies, pop bumpers, slingshot bumper assemblies, ramps, ball trough and associated parts, and any other parts that are installed on the playfield- top and bottom sides.
All metal parts removed from playfield have been hand cleaned and polished to remove unsightly ball marks and restore original bright shiny finish, including refinishing of stainless steel ball guides using our own proprietary in-house metal restoration process.
Metal posts polished/shined including hex posts and standoff posts used throughout playfield.
All ramps have been completely removed and fully disassembled into all of their individual parts, including having wiring harnesses and switches/plugs removed for proper cleaning. Ramps cleaned, polished, and all associated hardware and accessory parts cleaned or replaced, and reassembled.
All light bulb inserts (or "lenses") in playfield surface cleaned and polished for maximum shine and light penetration.
Fender washers installed under top and bottom edges of slingshot bumper plastics to protect them from cracking/breaking from airborne balls.
Standup targets on playfield have been removed from game and fully cleaned- front and back. New foam rubber backing installed on all targets.
New target decals installed on all targets- standup targets, drop targets, spinner target.
Both slingshot bumper assemblies have had their detector switches removed and hand-cleaned and polished to restore finish.
All playfield plastic posts removed and cleaned by hand with detergent and brush to remove any wax, dirt, grime, or leftover cleaner. Damaged posts replaced with new, where necessary.

DeoxIT anti-oxidant compound applied to vital connector pins on boards in backbox for improved connections and added reliability.
List of New Parts on This Game:
A lot of large and small parts are typically replaced anytime a game is fully restored like this one, and this list may not reflect all of the actual parts used in the process, so should be considered an incomplete or "partial" list. Shipping/freight costs for obtaining many of the parts listed below may also not be included, so would be considered additional costs invested.
$110.00 value: New 16-digit alpha-numeric score display tubes installed.

Description
Overall view.
Main cabinet- left side. Solid blue portions of main cabinet and backbox have all been repainted on this game to restore the original look. Detailed artwork is original and in good condition with few signs of past use.
Main cabinet- right side. Legs feature brand new leg bolts, leg levelers, and protective leg pads to protect cabinet finish. Note new flipper buttons also. Cabinet side-rails and backbox hinges have been repainted in original semi-gloss black enamel, as have all hardware parts (bolts/screws) to restore factory finish.
Front of main cabinet, coin door. Coin door has been fully restored including full tear-down with all parts cleaned/reconditioned, and all black parts repainted in original factory semi-gloss black enamel paint. All wiring and parts have been cleaned and reassembled along with working coin mechanisms (U.S. quarters) so game can be operated with coins, or on "free play"- whichever you prefer.
Ball shooter housing has been replaced with brand new chrome housing. Lockdown bar on front of game is brand new.
Backbox- left side. Solid blue areas on backbox have also been fully repainted in gloss blue enamel, to restore factory look. Detailed artwork is original and in good shape. Some spots have been touched-up with paint, but a few average minor nicks/chips from use/handling over the years are still present on this previously-used game.
Backbox- right side.
Back side of game. Also fully repainted, and features brand new white nylon gliders installed on the "skids" on the main cabinet back, and new backbox latch decal as well.
Backbox- front view. Backglass on this game is original and in excellent shape with very few signs of past use/handling. Very well-preserved. Speaker panel is in great shape with all-new light bulbs installed behind center panel.
Back side of backglass. Original artwork is in great condition with no major blemishes or scratches/scuffs. Some of the white backing has worn off behind the "Back to the Future" words but is not unsightly when viewed from the front side. No cracks, flaking, or lifting are present in the rest of the artwork ("crack" looking marks in the upper left area are not blemishes- they are the back side of the lightning bolts in the artwork that can be seen on the front side).
Backbox insert panel and score display. Both 16-digit score displays have been replaced with brand new units in this game- a very expensive and time-consuming task, but will last and work well for many more years to come.
Backbox interior- circuit boards. All boards have been gone through and upgraded/repaired as needed, including upgraded power supply components for added performance and reliability, and worn connectors replaced with heavy-duty parts for reliable operation and reduced heat buildup. A remote-mount battery kit has been installed for the MPU board which gets the memory backup batteries off the board (as originally designed) and places them in a holder on the back of the insert panel. This protects the valuable MPU board from corrosion damage should the batteries ever go neglected and leak (a common and costly problem in most pinball machines with board-mounted memory backup batteries).
Main cabinet interior. Everything visible here has also been removed from the game, overhauled/cleaned/rebuilt and reinstalled. A new replay knocker assembly has been installed in the main cabinet to replace the original which was missing when we received the game. Lockdown bar latch has been reconditioned and repainted and has a new "Install 3 balls" decal. Game includes brand new operation/instruction manual with parts listings and fold-out wiring diagrams and schematics.
