Picked up an aftermarket MPU and got this one going again real quick.
Besides the new MPU and some cleaning and rubber, the only thing it really needed was a lot of connector rework, and clean up on a few old splices.
For the smaller .100″/2.54mm pitch KK 254 connectors, Molex 08-50-0114 contacts were what I used. For the larger .156″/3.96mm pitch KK 396, Molex Trifurcon 08-52-0125 contacts.

Besides Night Rider I’ve been digging up a bunch of long dormant projects in the shop, including a Williams Defender. I’ll post more about that one as I get deeper into it.
Haven’t been getting out of the house much these past few months except to get groceries, what with that deadly global pandemic and all. But I’ve masked up and made a few exceptions to pick up a couple more projects to keep busy with while I’ve got all this indoor time.
First is this wonderful condition 1979 Atari Asteroids upright, found out at the coast. The owner had bought it from a mall arcade many years ago and had it in a spare room, and was selling it now as they began home renovations and were tired of it getting in the way. It plays but the monitor image is collapsed and the sound is missing. Pretty typical issues for this game, with well documented repairs, and the price was very sweet.
Second is this 1977 Bally Night Rider. My dad has had one of these around since before I was born and I was fascinated by it even before I could reach the flippers. I’ve wanted one of my own for quite a while, but hadn’t had any luck, missing out on two that turned up locally in years past. I put another want ad up a bit ago though, and got a promising lead from a local operator. Agreed to a deal sight unseen since it was buried in storage. Once I got it home and cleaned up I was pleasantly surprised.
Cosmetically it’s in great shape aside from some wear up in the pop bumpers, back glass is minty. “Needs boards” turned out to mean just an MPU, everything else is there and looks usable.
Caught a few interesting pieces this past weekend. Loading them out of a hundred degree warehouse wasn’t a treat, but it was worth the effort.
First is what started as a dedicated Nintendo R-Type upright. Serial number is quite low, but it wasn’t exactly a common game either.
At some point it received a conversion to Golden Axe 2 that looks a lot messier than it is. The wiring was all terminated nicely so I can clip a Nintendo harness right back into place on the original connectors that were left intact. The coin door and vault were pretty messed up or absent but I’ve got spares I salvaged from some destroyed cabs at another warehouse years ago that will be a good match.
With some cleaning and the installation of a few parts it’s already looking most of the way there.
The second grab is another example of the purpose designed conversion kits that many manufacturers put out for the ubiquitous Pac Man and Ms Pac Man as they got on in years and stopped earning once the fever around those titles broke.
It’s a Nintendo conversion kit for the Vs. multi-game system. Similar in character to the Bally Sente conversion kit for these cabs, it takes a different approach to reconfiguring the monitor orientation and changing out the control panel.
This one clearly earned its keep as Pac Man before the transformation with almost twenty thousand plays on the clock, likely paying for itself twice over in its original incarnation.
The conversion was quite cleanly executed, though the Nintendo switching power supply has at some point been swapped for a generic model which was left hanging against the PCB cage.
Not a lot is retained of the original Midway internals. Portions of the power panel, AC wiring, and the Wells Gardner K4600 monitor are all that came along for the ride. The monitor has the maze burn you’d expect from any Pac Man game but it’s hidden pretty well by the smoked plexiglass panel that goes in front. Interestingly a standard Nintendo isolation transformer was included with the kit, though its 100V output is left unused and the Midway transformer is used to isolate power to the monitor.
A Nintendo video inverter and sound amp board is used to adapt the signal from the Vs. PCB to the output hardware in the cabinet.
Detritus in the cab says this one hung around in the Pacific Northwest, nearby one of the outposts of the Fred Meyer chain. The straw trick (“It has been brought to our attention that a flattened straw or similar object can be passed through the center opening in the upper hinge. If the object makes contact with the coin switch, it can be used to run up multiple credits.”) to getting free credits on Nintendo games must have made the rounds too, though whoever applied it didn’t realize that it only works on original Nintendo coin doors. We can also see the Vs. boardset played host to a few different titles over time, with Ice Climbers and Mach Rider in evidence.
This one will stay converted, though I’ll swap in a Dr. Mario daughterboard for the Super Mario Bros. chipset.
