1969 Williams Expo


When we first got this classic pinball machine it was in need of a lot of TLC. It had may owner over the last 20 years, changing hands at least 4 times. Each new owner trying their best to get this machine working, but unfortunately each person had different ideas of how to go about working on it.

First, most of the lacing cord on the wire harnesses had been removed. lacing cord is a waxed linen cord that companies used to build wire harnesses before there were tie wraps (although there are still some places that still use it today). Instead of nice neat wire harnesses, the wiring was a mess. I amuse the lacing cord was removed to make troubleshooting and following the schematics easier, since when working on machines this old with cloth covered wire, the colors fade after time and are had to figure out. I cleaned up the wire harness using tie wraps and made sure that the connectors that go from the body to the head had the proper strain relief.

Once all the issues with the main wire harness were taken care of I tried to play a game. I could not get the game to start due to the coin door being so badly hacked up. Not only were most of the wires cut, broken, or covered in electrical tape, but many of the parts were missing. Also, a lot of the metal parts were rusty. Since I was planing on setting the game up for free play, I decided to remove most of the coin door parts instead of truing to re-wire the door, locate the missing parts, and paint or replace the rusty parts. In the end it make for simpler troubleshooting and operation with those unneeded part removed.

Now that I was finally able to get a credit on the machine I played a game to see what needed to be done. There were a few little things that didn't work, but the biggest issue was the ball count would not advance past ball one. This was because like most of electromechanical games of this age, all the grease on the stepper units had become a sticky mess. I took apart each stepper unit, soaked each part in cleaner, then reassembled and adjusted each one. Now most of the little things that didn't work originally started working but the ball count would still not advance. I believe this may have been an issue one of the previous owners had and may have been why the lacing cord had been cut. I followed the schematics line by line, and found that someone had bent all of the contacts associated with the Ball Count unit out of shape. Once I properly adjusted all of the contacts the Ball Count finally started working.


Now that the game was finally working and playable it was time to move onto the cosmetics. It looked as if one (or more) of the previous owners did a little cosmetic work the playfield and the cabinet. On the playfield there was a spot where someone had polyurethane over some wear spots. While it was not perfect there was little I could do to improve it, so I left it alone. I removed everything from the playfeild, cleaned all the parts and plastics, replaced all the bad bulbs and rubber, and put it all back together again. Both my wife and Daughter helped clean and wax the palyfield! The cabinet had some holes in the front where the original operator probably had a bar mounted across the coin door to prevent someone from breaking into the machine. These holes were poorly filled with wood filler. I sanded down these spots, properly filled them, and then painted the front. Since I was no repainting the whole cabinet I only painted the orange to keep the worn look the rest of the cabinet had. I also painted the Backbox frame to give the machine a better look.

My daughter is now at an age where she enjoys helping work on games. She is also fortunate enough to be able to attend an amazing enrichment program for academics and art called YDO (Youth Development Organization). YDO is a citywide non-profit organization committed to providing enrichment activities and long-term support for motivated students in Lawrence, MA. And when their annual fund raiser "The Taste" rolled around this year, my family and I overwhelmingly decided to donate this beautifully restored machine to their live charity auction. When the bidding was done we raised $500 from the sale of this machine!
