Specializing on WPC/90’s games, I work on and perform board repair for all major solid state machines from the 80’s to moderns. You can find various posts about projects here on my website.
Based out of Arlington, TX, I perform house calls and take games in on request that need extensive work.
I’m also a competitive tournament player, you can find me at major events throughout the greater DFW metroplex.

The Machine This Bally Twilight Zone (1993) came to me from Oklahoma City, where it had spent over two decades sitting in an outdoor shop. Years of red dust and grime had worked their way into every corner of the machine, and it needed serious attention before it could play again. Note the Oklahoma tax stamp from 1998 on the apron, and the owner said the game has essentially been kept in storage at his shop since. All the boards inside were numbers-matching original and had no work done prior which is pretty astonishing. ...
The Board This WPC-89 MPU came out of a Judge Dredd. The game had stopped booting entirely and was showing intermittent direct switch issues before it gave up — two classic symptoms that point straight to MPU corrosion damage. Diagnosis On WPC-89 MPUs, battery corrosion is one of the most common failure points. The onboard batteries leak if not replaced often, and the corrosion spreads across the board under the batteries, taking out the switch matrix components and traces underneath. In this case the corrosion had only reached U16, one of the LM339 comparator ICs responsible for the direct switch inputs, which explained the switch issues prior to the full boot failure. ...
