So onto some pictures of the basement remodel. The first series of pictures is the drywall hung, prior to taping and mudding. Click on each image for a larger version:

The plans for the bar area have changed slightly since the original design (I’ve included a picture of the original design below for reference). Instead of a full bar, which I felt would consume far too much floor space, I’m simply going to do a wall of cabinets and a 8′ countertop between the opening for the refrigerator and opening between the two rooms. What is depicted as the “bar back” in the image will be the only cabinets going in, but it will extend almost to the opening. The freezer will be going into the storage room once all my games are pulled out of it. Sorry these photos are a little lower quality, I took them with my phone, but here is the area taped, sanded and primed:

This last weekend we shot a knock-down texture on the ceiling. It’s not my favorite texture in the world, but it matches what is in the rest of the house. It was difficult to get pictures of it but you get the idea:

There are four 6 1/2″ ceiling speakers. One pair in the bar and TV area and the other pair in the game area. The speakers are hooked to my main stereo and each pair can be turned on or off independently. I also have an old Turtle Beach Audiotron that streams all of my mp3 files from a NAS drive through my receiver. The Audiotron can be controlled remotely via my iPad. I wish they still made the Audiotron, the thing is a tank! I opted not to do a surround sound setup. The TV upstairs has surround sound so that will have to suffice. I’m ready to get this project done. I haven’t played a game in months and am eager to restore the Centiped cabinet and then start on DK and DK Jr. I hope to have everything complete by mid-February. As always, you can view the entire gallery of pictures from my basement remodel here. Stay tuned….

I’ve been prepping the control panel for a few days. Obviously, the first step was to remove the old control panel overlay. Surprisingly, I was able to peel it off without much trouble. Unfortunately, all of the adhesive was still on the control panel. I did quite a bit of research to determine the best way to remove the adhesive. Since I was working in the basement I needed something that was relatively odor free. I saw several suggestions for a product called Citristrip which I found in a quart sized container at my local WalMart. The Citristrip was brushed onto the adhesive and I let it set for about 6 hours. You can apparently let it sit for up to 24 hours. Using a putty knife to scrape, the old adhesive slid right off. I rinsed the control panel off with water and dried it with a hair dryer then sanded both the front and back sides down to bare metal. I had to do a lot of hand sanding on the back side as my sander wouldn’t fit. I used 100 grit paper until the panel was bare, then hit it with 150 grit paper. Just for good measure, I sanded one more time with 220 grit paper (click on each image for a larger version):

I then decided to hit the control panel with a couple layers of Rustoleum paint. There’s debate about the necessity of this step but since my panel had some rust prior to sanding, I opted for it as the Rustoleum should prohibit rust in the future. I applied one layer of Rustoleum semi-gloss black spray paint to the control panel and waited. 8 hours later, I was still waiting as the paint was tacky and had not set up yet. I had to wait two days for the paint to dry. I decided to look for another alternative and found the Rustoleum “Professional” line of paints. It is advertised as having better spray coverage and a much faster drying time. I can attest to both and it’s only about $1 more than the regular Rustoleum paint. I’ll be using this on all of my projects from here on out:

Now the nerve wracking part… installation of the new overlay. As I said, you only get one shot at doing this right. Here was my plan of attack: I took the tube from a roll of paper towels and cut it in 3 inch sections. I made a cut lengthwise in each section which allowed me to vary the width of the tube. I put a tube in the player 1 start hole, the player 2 start hole and the fire button hole. The overlay sat down over the tubes and was aligned perfectly. I then placed the trackball bolts into their holes to align the right side of the overlay. I then put masking tape on both sides of the control panel overlay just above the bend to the front. This held everything in place. I peeled back the backing paper down to the masking tape and applied the middle section of the overlay first working out to each side. Once the top was in place, I removed the masking tape, took off the rest of the backing paper and finished the job. A couple of passes with a j-roller assured good adhesion. I installed the new trackball, the player 1 and 2 start buttons and the fire button. I didn’t take any pictures of the process as I was too worried about screwing up! I also forgot to buy a new white button but will do so in the near future.

That’s it. I made it! No bubbles and no misalignment. I probably spent 1/2 hour stripped the old control panel overlay and removing the adhesive, 45 minutes sanding, 1/2 hour painting (excluding wait times for drying) and an hour installing the new overlay and putting the panel back together. I’m not sure I’ll be any less nervous the next time but as Mr. Rogers used to sing, just “take your time and do it right”.

The monitor that came with the cabinet had a serious case of burn in. So bad, one would probably think they could play without even turning the machine on. I decided to use my last spare monitor to replace it. The spare monitor had a little burn but I don’t think it will be noticeable while playing the game. I hooked up the spare monitor, powered it on and immediately blew a fuse on the monitor chassis. That’s a hell of a start. I found a replacement fuse and powered on the monitor only to find that the screen was reversed side to side, as looking at it in a mirror. I knew that I had to flip the vertical yoke wires to get the image correct. Bob Roberts does a better job of explaining this than I ever could.  Once I had the image oriented correctly and adjusted, I installed the monitor into the cabinet (click on each image for a larger version):

I think everyone will agree that the new monitor is a huge improvement. I did learn a lesson last night that I can’t believe hasn’t occurred to me before. It’s much easier to adjust a monitor outside of the cabinet than it is inside the cabinet! That’s all of the work I accomplished last night. I did get my parts ready to begin working on the control panel:

I’ve got a few vacation days coming up so hopefully I can get the control panel knocked out. If it gets above freezing, I might even start on some of the cosmetic repairs to the cabinet.

There are two things pretty common amongst Ms. Pac-Man cabinets that saw a lot of play on location. Flaking / destroyed paint and burn on the monitor. Mine has both. Fortunately, the monitor burn is only noticeable when the game is off. You really can’t see it when the game is powered on.

Someone tried to repaint a portion of the cabinet but did a poor job of matching the paint. If I decide to do a total restoration on this cabinet, there are really only two options. Option one is to obtain vinyl side art. This is usually sold in a 3 piece set. One piece to cover the entire left side, one piece to cover the entire right side and one piece that covers the front of the cabinet by the coin door. There are a few spots on the cabinet that would not be covered in vinyl and I’d imagine that getting a blue paint to exactly match the vinyl would be difficult.

Option two is to obtain a set of stencils and re-stencil all of the artwork on the cabinet. While it’s not really anymore costly than option one (provided you already have the needed tools) it is a hell of a lot more time consuming (estimated to be between 40 and 60 hours).  I won’t go into the details of re-stenciling a cabinet, but theres a great tutorial over at Jeff Rothe’s site.  Give it a read if your interested.  Here’s what my cabinet looks like (click on each image for a larger version):

It’s not too difficult to see the badly executed paint touch-up attempts. I’m not sure what happened that caused the cabinet to lose that much paint but I’ll eventually have to deal with it or sandwich it between two games so it can’t be seen. Unfortunately, the front artwork has a number of touch-up attempts as well but not near as much as the sides. The marquee is in very good condition.  For some reason, the back door doesn’t look right to me.  I’m not sure if it’s original or someone simply made a replacement.  Unfortunately, all tags and serial numbers are missing from the cabinet.

The control panel is in pretty good shape and probably just needs a good cleaning. You can see your first glimpse of the monitor burn in the control panel picture. The second pictures shows a full on shot of the monitor burn. You’ll also notice that it just has a generic bezel and not the proper Ms. Pac-Man bezel. This will be replaced if I can find one. I won’t pay the price for an “official” licensed reproduction so hopefully I can find a used original in nice condition. As you can see in the last picture, the monitor burn isn’t really noticeable when the game is running. It will work for now. Hopefully I can find a nice replacement monitor in the future.

I mentioned in my post yesterday that all of the original wiring had been removed and a Jamma wiring harness installed. In the board picture below, you can clearly see the Jamma to Ms. Pac-Man adapter. Finding original wiring is low on my priority list. You’ll also notice that the original power transformer has been replaced with a switching power supply. No big deal and probably more reliable. Since nobody knows what is on the inside, it’s really not important. The only time all of that may come in to play is if I decide to sell the game to another collector. I’d prefer all original, but I can live with it. At least it works!

I’m going to have to do a lot of thinking about the path I want to take with this one. Right now, I’m just going to enjoy playing it!

I haven’t had a chance to get any pictures yet. I’ll try to get some tonight. If you don’t know the history of Ms. Pac-Man, here is her entry in the Killer List of Video Games. As is customary, here are the scans of the original marketing flyers for Ms. Pac-Man, courtesty of ArcadeFlyers.com:

As usual, I’ve set up a dedicated photo gallery just for Ms. Pac-Man. Check back tomorrow for some pictures of the cabinet!

I started working on the basement again in October and have made pretty good progress. New recessed lights have been installed to replace the hideous ceiling fans that the previous owner had installed. I still need to run the wiring from the switches to the lights. Most of the insulation has been put into place. All of the wiring to the outlets is in place as well as Cat-5 cable and cable for the satellite system.

I decided to put down a sub-floor just to eliminate the feeling of being in a basement. I found a product locally which is a 24 millimeter membrane with dimples that you place on the concrete. It acts as a moisture barrier and air gap and allows the concrete to breathe. On top of the membrane, you lay normal plywood just like you would any other sub-floor. This is the product I purchased. Because of a lack of storage space, I can only work on half of the flooring at any given time. I have half complete. I’ll need to move games and a few other items around to finish the other half. Before I move the games around, I’m going to go ahead and install the drywall on the half with the sub-floor. If mother nature cooperates, I’ll hopefully be picking up a load of drywall on my way home from work tonight. Unfortunately, it’s supposed to start raining and snowing sometime today. I’ll have some updated pictures after the weekend.

On the arcade front, I really haven’t done anything but I have been stockpiling parts in hopes of resuming some projects after the basement work progresses. Here’s what I have lined up, in order of priority:

Centipede

I have all of the parts to completely restore this cabinet. Phoenix Arcade had a Thanksgiving sale on Centipede side art, so I picked up a set. I picked up a marquee from a fellow collector. Another collector was parting out a Centipede so I grabbed his speaker & light assembly to replace the one from mine that was covered in mouse excrement. Finally, I have a new trackball and control panel overlay ready to be installed. The only thing this game really needs is a new monitor tube. I’ve been looking, but no luck yet. Centipede will be getting a complete restoration similar to my Dig Dug restoration.

Donkey Kong

This one will also be getting a full restoration. I still have the new control panel & joystick that I received last Christmas. It still hasn’t been installed. I have cap kits for both the monitor and audio board to install. I have two NOS coin mechs for the coin door. All I really need for this one is the side art. I’m considering a new new monitor bezel and marquee as well.

Donkey Kong Jr

A full restoration lies ahead for this Donkey Kong cabinet, converted to Jr. I really don’t have any parts for this yet, but do have a high score save kit to install on the board. It will be getting a new coat of paint in Jr orange, new marquee, control panel, bezel and side art.

Golden Tee Conversion

This one will get the hole repaired where the bill changer used to be, as well as a few other minor cabinet repairs, and be good to go.

Missile Command

Nothing major with this one. I’ve got a multigame kit to install on the board which allows you to play both Missile Command and Super Missile Attack. It saves high scores too!

That’s all for now. Hopefully some work actually gets accomplished this year! Finally, hats off to Jeff Rothe at Rotheblog for the new, free WordPress theme. I’m diggin’ it!

Fast forward 7 months and the cabinet has not been touched and is sitting in my garage. Much to my wife’s displeasure, this kept me from moving the lawn furniture into the garage over the winter! Over the weekend, I decided to move the cabinet into the basement and start working on it. I did not move the lawn furniture into the garage.

I shopped around for a few months looking for an original Sanyo 20ez monitor to put in the cabinet but didn’t have any luck. I found one on E-bay that went for more than I was willing to spend and had a few offers to ship monitors to me but they all needed some form of repair. I decided to use a spare Wells Gardner K7000 monitor that I had sitting around. It took me all of 5 seconds to realize that the mounting holes on the K7000 monitor did not line up with the mounting holes on the Nintendo mounting brackets. As a matter of fact, the K7000 did not have any top or bottom mounting holes at all.

It became apparent that I would have to bolt the monitor to the monitor shelf in the cabinet. I took a few measurements to find the center of the monitor shelf and also the center of the monitor itself. I then measured the distance that the monitor in my Donkey Kong cabinet stuck out from this shelf (towards the front of the cabinet). The monitor was bolted to the shelf in almost the exact orientation as the monitor in my Donkey Kong cabinet. If I had to guess (because I didn’t measure) the monitor in this cabinet probably sits a bit lower than the monitor is supposed to but once everything is done, I don’t think it will be apparent. Here are a couple of pictures of the monitor bolted into place:

In the first picture above, you can see the original Nintendo monitor mounting bracket at the top of the monitor. You can also see that the K7000 sits short of this bracket. In the second picture you can see the bolt locations on the lower left and right sides of the monitor frame. There are also two bolts at the top that can’t be seen in this picture.

Once the monitor was mounted, I needed to find a spot to place the 120 volt isolation transformer for the K7000. 20ez monitors used 100 volt transformers so I couldn’t use the one currently located in the cabinet. I located a spot near the power supply for the isolation transformer, mounted it and then connected it to the 120 volt and ground terminals of the terminal block. Here’s a picture of the isolation transformer mounted inside the cabinet. The isolation transformer has the 4 red wires attached to it…two coming in from the terminal block and two going out to the monitor. The terminal block is to the far right of the picture:

One thing that is needed on monitors in a Donkey Kong/Donkey Kong Jr cabinet is an inverter board. Without an inverter board, the image on the monitor will appear to be a negative of what should actually be there. The majority of the image will appear to be white if the inverter board is not present. I had previously purchased an inverter board from Mike’s Arcade and made the necessary connections to it.  The inverter board requried 12 volts DC to run, so I temporarily “borrowed” 12 volts from pin 4 of the 9 pin CPU connector at the power supply.  After a bit of monitor tweeking, the image is stable and clear…my blurry picture does not do it justice:

The final picture above is the front of the cabinet that will eventually become my dedicated Donkey Kong Jr machine. It is complete with a Donkey Kong marquee and bezel but those were removed while I worked on the monitor. Right now, the wiring to the inverter board and monitor is a bit of a “hack job” as I wanted to test everything before making it permanent. I will eventually clean up the wiring and add molex connectors as time allows. As usual, a dedicated photo gallery has been set up for work on the Donkey Kong Jr cabinet. Stay tuned….

Each section was completely disassembled. All metal parts were thrown in a vibratory tumbler with walnut media for a thorough cleaning. Plastic parts were cleaned with Novus 2, a polish specifically designed to remove fine scratches and haziness.

Cleaning the playfield was a multi-step process. It was initially cleaned with Simple Green cleaner. After that, I cleaned the playfield lightly with a Mr. Clean Magic Eraser. Be very careful with the Magic Eraser! If you have areas of wear, which I certainly did, the Magic Eraser will continue to eat paint off of these areas. Do not go crazy with it, but it’s great for removing ball marks. Following the Magic Eraser, I buffed the playfied with Novus 2 polish and finally 4 coats of carnauba wax were applied.

Below is the lower portion of the playfield, before cleaning and after cleaning. In the before photo, the dirt and grime is most noticeable in the right side exit lane, near the “300 Down Post” exit lane. It’s also pretty noticeable around the right side kick area and around the flippers. Most of this dirt and grime is gone in the after picture:

In the middle of the playfield, the clean playfield is most noticeable at the exit of the right side lane behind the drop targets. In the before photo, you can see a trail of dirt headed from the exit of this lane, across the Blackhawks flag and towards the flippers. In the after photo, this dirt and grime is gone:

There’s not a whole lot of discernible difference on the top portion of the playfield. The biggest difference is the installation of brand new plastic caps on each pop bumper. However, if you look at the latch that keeps the ball rolling back down the shot lane and the metal on the rebound bumper (upper left) in both the before and after photos, you can see the difference that the vibratory tumbler makes:

You’ll notice that I also replaced all of the white rubbers on the machine as well as the red flipper rubbers. I also replaced two solenoids on the underside of the playfield, one for the upper left flipper and one for the left side drop target bank. The right side upper flipper was rewired to remove about four wire splices. There is still one splice, as the wire was too short to attach to the solenoid, but I put a plastic wire cap on it to keep it from shorting against other wires.

The left side drop target bank is still not functional. I traced the problem back to a fried resistor on the solenoid driver board. In the picture below, the fried resistor is just below the “9″ on the tape piece:

I have replacement parts ordered for the fried resistor, but they haven’t arrived yet. I will actually be replacing every transistor, resistor and diode on that board. As it stands right now, I have between 25-30 hours invested in the disassembly, cleaning and reassembly of the playfield parts. I can tell you this….pinball machines are much more work than arcade games. That’s all for now, I’ll wait for my proofreader to send me edits to this post!

Placed in the backbox and illuminated, the backglass shows a lot more wear than it does out of the cabinet. The biggest thing I plan to do right now is apply some Krylon Triple Thick clear glaze to prevent further damage from occurring. The artwork on the cabinet is in decent shape, but the entire thing still needs a good cleaning, as does the playfield:

Right now, the only items still not working on the playfield can be seen in the 4th picture above. The left side drop targets do not work and the center pop bumper is not working. All of the drop targets need to be replaced as they don’t match and two on the right side have broken connectors. Underneath the playfield is where things get interesting and where most of the problems reside:

If you look closely at the blue wires in the last picture, you’ll quickly notice the problem.  Instead of making proper connections to the components, someone hacked a wire to a wire to a wire to connect the component and then left the soldered bare ends of the wires floating around in the cabinet.  The fuse holder that I mentioned in my last post is located directly above the blue wire rat’s nest.  When I changed the holder, I apparently bumped these blue wires causing two of them to short together, which in turn caused the left side flippers to quite working.  I’ve found at least 3 other spots in the cabinet where the wiring has been hacked just a bad, so I’m not sure if my non-working parts are part faults or wiring faults.  I’m not going to work any further until I repair all of the faulty wiring I can find.  That’s all for now…

I sent an inquiry to the seller and learned that the machine was a Power Play machine manufactured by Bally in 1978.  The seller also gave some additional information on the condition of the machine.  It would power on, and the lights would come on but the rest of the game was essentially dead.  The machine was complete with the exception of the glass, which I discovered I could replace for about $45.

We reached an agreement on price and I picked up the machine on Monday (my Christmas present to myself).  Power Play is a solid state game with a hockey theme featuring then Chicago Blackhawks player Bobby Orr.  While it’s a solid state game, it has the look and feel of an electro-mechanical game.

Cosmetically, the machine is in decent shape but needs a good cleaning.  All of the playfield rubbers need to be replaced and a few bulbs are burnt.  The backglass has some flaking but is in decent shape.  I’ll take some pictures this evening and hopefully have them posted tomorrow.

Once I got the machine in my basement, I began to try and track down some of the issues.  I started by checking the voltages on the various boards in the backbox and got decent readings on all of the test points.  I checked all of the fuses in the backbox and determined they were all good.  I powered on the machine and could start a new game, however, the only thing that worked on the playfield was the rollover buttons and the flippers.  I located a fuse on the underside of the playfield and upon visual inspection, it looked good. 

As I looked closer at the fuse holder, I discovered that one of the holder legs was broken and not making contact with the fuse.  I did a continuity check from the wires leading to this holder and confirmed that there was no continuity.  I had a spare fuse holder handy, so I replaced the broken one and powered the machine on.  It sprung to life…with only a few elements now not working.  The left side flippers aren’t working, the left side drop targets aren’t working and the center pop bumper is not working.

I’ve already ordered a batch of parts for the machine, including a new pinball, some playfield cleaner and a new rubber set.  This will be a learning experience for me as pinballs are quite different from arcade machines with all of the coils, switches, etc.  It should be a fun project.

In keeping with my tradition, here are the original marketing flyers for Power Play pinball:
