    @gtoal On the back side I just used some good clear label/packaging tape. Doesn't show up when installed on vec. If I was going to go further with these, was thinking of getting sheets of paper backed label covers and cutting custom shaped pieces for the smaller items. Battlezone and others with score window at top is just one long piece trimmed to edge of overlay. The trick to using rolled tape is to pull a long length off swiftly to not damage the glue on the tape so that you have a clean clear piece. Armor attack is just the grid cut out in blue and with small pieces of tape affixed to the reverse side of yellow. :p Same with WoW. Hot lamination would not go well for sure. Edge to edge gluing crossed my mind, but never attempted knowing that would fail as well. They do hold up well though, never considered the custom ones as a polished product though. I enjoy the hell out of them for myself. And sadly I'm sitting on material to make 20 more sets of the colored overlays I was selling before, but it is all garbage, warps in colors, not fully transparent, was a gut punch and huge money loss. Experimented with some other sources and it's like everyone has the same bad batch. good day.
  2. Hey, Chopper - hope you're well, just wanted to give you a heads-up, I used some of your YT footage of Midway's Table Tennis in my documentary on attempts to turn Pong into a mechanical game - hope you like it!

  3. Very cool stuff, but my unit didn't have side port and I wanted s-vid, L/R audio (it's mono but quick hook up for my system) and composite. You might be the person to run with this idea and offer a 3rd option for the folk that do the UAV install. Wish I was smart enough for this 3d printing thingamajigs. good day.
  4. @StephenJ, frogger doesn't fit within the spirit of what he's doing. That game only has options for 1 or 2 player and difficulty. Where a game like space invaders has over 100 different game options, variations and combinations that benefits tremendously from a start menu. good day.
  5. I'll get some inside pics when I go to work on the controls again. Almost thought there was no hope for it when I first got it a couple years ago, it's one large PCB and the double sided tape on PCB retainers in center let loose. The player 1 & 2 pots are hard soldered to PCB and 3 & 4 have wires, but both player 1 & 2 pots got bent up separated in half due to the weight and whole PCB was bouncing around in case. If I can fix the controls, this will be a pretty nice save. If you need pics or anything hit me up. I have the boxes for the radio shack, speedway and pong sports IV units. good day.
  6. Trying to plow through things from my todo pile before spring hits and the backyard RC track reopens. I've gathered these random units cheap over the last 4 years. They all had random issues ranging from crappy video, jittery pots, locked sounds, broken pot, non working switches and just over all filthy. The major save for me is the coleco telstar arcade, had one growing up, it was a great option for a single mother raising 3 kids that couldn't afford a VCS at the time. Aside from RF tweaking, changing shifter switch, pot and switch cleaning, it had a sound issue. When it was supposed to be a blip or bloop it would output a crash sound. So something on the sound board was locked, figured out the signal trigger inputs and after looking at spec sheets narrowed it down to 2 chips. Found them online over a year ago, but finally did the repair with perfect success. The tennis game now blips and bloops instead of the crash sound. I'm proud to have this example in my collection. The radio shack Electronic TV Scoreboard had a broken pot in the main unit. The sweep had come separated from the plastic shaft. Thankfully the plastic was real receptive to CA glue and got the sweep back in place for good. The speedway RF unit was toast, just could not be tuned, thankfully this is one of them units that looks sweet through composite. Lifted center pin from RF out jack and tapped from the video input. I'm only getting action from 1 of the 4 pots, I've narrowed it down to the comparator chip. Will hunt for one and hope for a fix. Great weekend to finally get 4 out of 5 of my pong units ready for prime time and fully playable. Made great headway on the Telegames Speedway and saw a clean image for the first time, hope to solve the input issue. good day.
  7. Strip of double sided tape under header/pot and small piece just under the power input of UAV so the rest of board is floating above chip. Should be fine. Thought about top of RF thingy, but I did put shield back. Yeah, knew I was killing the audio to RF, no biggie at all. Last and final time the RF was connected was for the PP screen shot. :p Your guide was great though. good day.
  8. Finally added a 7800 to the collection last week, was just waiting for the right CL deal. Ordered a UAV after seeing how rough the RF signal is. I've done many mods to other consoles, but the case on the 7800 really is a bugger. Knowing how brittle the plastic is and also would never be happy with jack placement, I just didn't have the heart to take a drill to this thing. Had a 9v battery enclosure hanging out in the parts bin and got the idea to use that as a jack box for the unit. Held on with some VHB tape, wires route through added hole in 9v box that lines up with the 2/3 switch opening. Header pins used for vid connections on UAV and audio line is soldered, easy to fish wires back out should any future repairs be needed. Someone that is savvy in the 3d print world could do a slim line box that would stick to the molding of the cable wrap on botton and have all jacks in one row. I'm just an idea guy, but really happy with the results, it's easy to hook up when needed and no drilling. The video quality is stunning with the UAV. good day.
  9. Chip looks original, 22nd week of 1983, and pretty normal for clean sweep. good day.
  10. You're making sure that the voltage is zeroed out when nothing is being drawn to the screen. Logic board generates digital signal and DAC converts to analog to drive the vector monitor, it's kinda like setting the idle on an old engine. There are some bad vids out there, best place to start is giving the vectrex service manual and read through a couple times, helped me a ton. It's like 40 pages long or so, covers in some detail of the operation of circuit, find it on console5 or other places. good day.
  11. Hope these get in the hands of people that have wanted one for an extended period (like myself) and not caving in to the secondary market. Thinkers and double uppers should get to the back of the line. good day.
  12. Driving controllers on atari vcs are not optical, the use a gray encoders. https://en.wikipedia.org/wiki/Gray_code That's the nicer encoder to have (doesn't feel as "ropey" as the more common pcb stack encoders). Comes apart real easy for cleaning with lightly prying the corner tabs. You can also reduce the friction by bending down the unused sweeps (see attached pic). After cleaning a spritz of deoxit on the pcb for lubrication is recomended. good day.
  13. There's some other cool TTL coin op stuff that wasn't exactly a video game. I have an Electro-Dart wall game from 1971 in my collection, main pcb is in the left unit and large multi pin cable connects to right unit for lamp operation. Fun game, on wireless remote you press and hold button while watching the animation of your dudes arm and release button/dart at right time to get bullseye or lesser score based on timing. There's no sound, you just have to picture a couple old dudes sitting at the bar of the VFW in 1972 passing the remote back and forth with 50¢ bets on each game. I've been meaning to shoot a good video of mine in operation, there's a couple other blair witch type vids on the tube already if you want the gist of the game. Wonder how many folks here have even heard of "wall games". good day.
  14. Was able to log some hours testing over the last week and I'll applaud their attempt, but something isn't right with the paddle portion. It has a strange feeling on the left side of the screen, almost like there's a different resolution interpretation of the pot beyond center left. Right side of screen seems ok, but all game failures were due to something off with left of center. I couldn't even get close to 1000 with the ranger on kaboom after hours of trying to adapt. Plugged in my trusty Sears video arcade II (modified for 2600) controller (pictured far right) and got 2225 on kaboom on the 3rd game and cleared 3 screens on avalanche. Also tried the standard paddle and had some fair scores, but I get in the groove with that 2800 controller on paddle games. Went back to ranger and it felt like crap again. It's not bad as a game pad with the joy and button, but paddle is not right, ermm left. :p Ain't no one gonna be setting any records with the ranger paddle, it will just piss you off. If you have a 2800 controller and are interested in wiring it for paddle on a 2600 see here: good day.
