    Service call to a Stern Playboy a couple of days ago. I took the MPU board in for repair to abate some alkaline corrosion from leaking batteries. Replaced with a lithium cell and installed NVRAM while I was there.


    Little bit of work to do on the playfield, too. The triangle motor wasn't stopping at the correct spots for "Splash" and "Triple Jackpot" awards. The switches underneath the assembly were out of adjustment. The clear plastic above the left ramp was missing. This resulted in shots to the ramp getting rejected most of the time. I fashioned a new plastic out of polycarbonate, drilled the mounting holes, and voila! Not as precise as a CNC cut plastic, sure, but not bad for an on-site repair either! Also installed a custom topper and wired it into the backbox. Changed a few rubbers and replaced a couple of switches to finish things off.


    Welcome back to the mansion!

    This was a relatively clean machine with a couple of niggling issues. The main one was the beacon topper wasn't working anymore. The motor that turns the reflector was jamming. Gottlieb used a widely available toy motor for this assembly, which is still available to buy from many Chinese electric motor suppliers (part no. EG-530AD-2F). To couple the motor shaft to the reflector base, cap the shaft with a rubber post cap. Spins like a dream now!


    There were also some inoperative switches. The cave-in drop targets needed adjusting. There is also an optical switch pair by the pop bumpers that most people don't know is even there. These opto boards needed reflowing to get them working. A flasher wasn't working, too. This was due to a dodgy connector under the playfield.


    Game is now playing nicely and is ready for sale!

    A service call turned workshop repair. This Solar City (Gottlieb, 1977) was not starting properly, nor was it working quite right when it did eventually start. Lots of work to get this machine up to scratch. Solar City is an unusual game because it shares the exact same playfield as six (!) other games. They are:



    Target Alpha is the game that people generally remember as more of these were made than any of the other varieties. However, the gameplay and playfield mechanisms are basically identical between them all.

    This machine was having switch issues. Half of the switches weren't working. Severe corrosion on the CPU board due to battery leakage was to blame. Duraleaks strike again! A new CPU board and connectors were installed and things were back to normal. Great to have Coin-Up Pinball around; an Aussie supplier of these CPU boards. A few other minor repairs and adjustments were also done. The most interesting was a lost ball which had gotten stuck in the ball trough.... it took a little while to find!

    New shaker motor installed! An awesome addition to the game which really makes you feel those shots to the crane.


    Some of the early SAM system games were made with a shaker motor option available, but the cabinets were not always prepared for installation of the assembly at the factory. As a result, you may need to drill the mounting holes and install tee-nuts so you can bolt the shaker motor into place. Ensure proper alignment and fitment as this is not a mechanism that you want to shake loose!

    I've never met a Johnny that didn't have issues with the Cyberglove assembly. This one was no different. It's an awesome mechanism, but finnicky. This one was having issues with the motor that drives the hand forward and back. It would randomly lock on, sending the glove forwards or backwards until it crashed into the end of the worm drive, blowing a fuse.


    So, time for a full rebuild. Disassembled and cleaned. Gearboxes cleaned and lubed. Encoder boards serviced. Turns out, the issue was faulty optical switches on one of the encoder boards. They were oddball optos that were not the correct part, and there was some hackery on the board. Installed new optos, new connectors, new transistors, and we're good to go again!
