Repair Station Upgrades

I recently added a B&K 575 IC Tester and a RCA Isotap II WP-27A to the Tranquility Base Arcade Repair Station. The B&K 575 expands the capability to test vintage CPU's as well as difficult to test 7400 series TTL chips. The RCA Isotap II WP-27A is a variable isolation transformer that will allow me to power up monitors such as the 100V Sanyo 20EZ and the 120V Wells-Gardner K4600 outside the cabinet and on the test bench with the same power source. New vintage test equipment to keep the arcade running smoothly makes this OP happy!

Battlezone PCB Repair Logs

2025 started with Tranquility Base Arcade tackling Battlezone board sets for back up and for friends who were having issues with theirs as well. Through the years I have always regarded Battlezone PCB’s as ‘difficult to work on’ especially with faults from the AUX PCB. With improved bench capabilities the last 5 years I started 2025 with renewed optimism to repair all the Battlezone boards piling up at the Repair Station! After a lengthy repair process for each board I’m happy to report “They all have been saved!” The FPGA and my old KK Signature II along with a special SA harness were key to completing the repairs. I have created a special link to summarize each of the board repairs in order to provide assistance to anyone working on a Battlezone boardset. A new link has been added to the Repair Station page or you can simply click here. Bring on the Super Tank as I’m ready to battle again!
