Comet is the last Williams System 9 game, from 1985. Theme is amusement park.

Cabinet is reasonably OK.

Playfield is quite badly worn. It remains to be seen if it can be repaired, or is this a spare parts game.

Backglass is OK.

Besides the worn out playfield, also the display power supply and two display glasses were broken. The power supply was easy to fix but new displays are not exactly cheap or easy to find. So for now this is a 2 player game.

System 9 electronics. CPU, driver and sound boards are combined into one big board.


The playfield is now cleaned and waxed, and new rubbers installed. It was time for some test playing. This is an OK game. Pity the playfield is so badly worn. After the first testing day, the game background music was playing in my head for many hours after playing :)

Cleaned playfield.


Taru painted the playfield, now it looks almost like new! Playfield is worn where the ball moves, like one seller used to say. So it is in this Comet also.

Some wear...

...where the ball moves!

Previous owner or the operator has tried to fix the playfield with white and yellow paint. The colors just dont match very well, and the accuracy hasn't been of top quality.

Lamp inserts are also worn.

It will need lots of work, but we decided in the beginning that there is no need to make the playfield look like new. And so Taru has painted the playfield every now and then, whenever she had spare time. And comparing the before and after pictures, you can't help but admire her professional work quality. If she only had a decently worn playfield to start with, the results would surely have been like new. But this was a good project to get some experience for next, hopefully smaller touchup job.

Looks nice!

Clear lacquer protects the new paint.

Good enough to play!

Mixing of colors suceeded very well. It sure wasn't easy to make the old shade of white, and of course the other colors are not available straight from bottle either. But now it is even difficult to tell what parts have been painted and what are original. Even the lamp insert texts are nicely done with black paint. Not a job for those with shaky hands. The small people graphics in gray areas were left undone, there are lots of people still on the playfield so it doesn't matter even if the amusement park looks a little less crowded now.

Wear? What wear?!

New displays were found, to replace the two that were broken. Now the game is in great condition!


Comet went on to the next owner. Hopefully it gives pleasure for long time!
