    Thank you for filming this, I really enjoy it! I repair a lot of retro computers and occasionally arcade PCBs, and... "It's always the logic chips!" seems to be a common response. Those logic chips seem to be very prone to failure, and I haven't quite figured out why!

    Some time ago i bought a box of "assorted arcade boards" with at least 12 arcade boards i bought myself a logic probe and a soldering station to try out if i can manage to fix the boards that don't work , most of them appears to be bootlegs but ive spotted a dragon ninja and a double dragon boards, it will be fun to try to identify wich games are the other ones

      I like to fix things with the minimum amount of tools, it's easier to understand and cheaper to do for the home hobbyist who might find a game somewhere and want to fix it themselves... I know a lot of folks have a more extended test bench but I don't know the knowledge or the desire really to get elite level, I want to keep it as simple as possible which I feel helps more people fix theirs that watch. My goal is to keep as many of these games (and other electronics too) out of the landfill as possible.

    I checked for ATCS on the train track that runs through your town. The line is called the R Line from Charlotte to Savannah, I believe, and there is only ATCS where the line goes through Columbia SC. There is a crossover there and they have ATCS on the air and there is a server feeding the data from those control points.
    It would show you when a train was heading north out of Columbia SC
    I have to check the North end of the line and see if in CLT there is coverage
    The line from Columbia through your town uses ABS ( Automatic Block Signals ) so there is nothing ATCS being transmitted for that segment.
    Looking at Google Earth I see they did install new block signals, but no ATCS
    I am in the same boat here in Pennsylvania
    The Reading Line has aaTCS out of Reading to West Laurel, then ABS all the way to the yard in Hellertown, even though there are control points on the line, they are not on the air.

    So I am certainly going to look at that website, but I recently purchased a Ms Pac-Man cocktail table. All original, I believe, with the ribbon, not modified, Bally's Midway 1981. It comes with Pac-Man / Ms Pac-Man manual so, it's all legit. The problem I'm having is Ms Pac-Man will bite a ghost and totally glitch out and show like a Tron grid (as my 12 yr old daughter calls it) and go back to the main menu where it says one or two player. If anyone can help out, any insight would be greatly appreciated. I'm a handyman that can fix anything in your house, but when it comes to electronics, I'm pretty much completely in the dark. Great video, you're the first light at the end of the tunnel I have found in dealing with this problem. And it doesn't glitch out all the time, but it'll go on these streaks where you can barely get through a few boards and it will glitch. Nite: Also I don't fully trust myself not to mess this up, so if anyone reading this who knows how to fix this stuff is anywhere around New Orleans let me know. I'm an hour outside of town and would gladly pay somebody for the testing and fix of our cocktail table Miss Pac-Man issue stated above. Hard to find people who work on this stuff anymore.

  • @zenguitarankh
    @zenguitarankh 4 года назад +1

    Thanks for this man! Is there another way to know if the leads are supposed to be high, low or pulsing aside from comparing another identical chip on the board? It doesn't look like it's on the schims.

    • @LyonsArcade
      @LyonsArcade  4 года назад

      Yes, if you gain an understanding of the circuit and what they're trying to accomplish, and then an understanding of the particular IC, you can know which it should be doing. So if for instance it's a buffer chip, the input mirrors the output, so your knowledge of that chip would inform you that the input and the output should look very similar (low/low, high/high, or pulse/pulse)... if a chip is inverting a signal, they should look opposite, etc. Once you work on several you start to understand the relationship between the chips, so what they're trying to accomplish with the ram/rom/etc. and it helps you know which ones should be active and which shouldn't. It kind of comes with time...

    Hey, Joe..... I was a pacman king back in the day, and the arcade was losing so much money when i played, (me and a black cop named Roscoe would tie up the game for hours...) that they finally ordered a new set of ROM's. i believe they were called "PUC 2". It had mazes with exits at the top and bottom, and mazes that were invisible. one maze, you could go inside the maze walls, but the ghosts could not. I have not been able to find any one who has seem these ROM's, or knows where to get them. I now own an original PacMan board, and would like to find a set of these ROM's, if possible. any ideas?

      It's because the voltage is so low on the circuit board... it's running at 5 volts DC which is considered 'low voltage', it's the same voltage like a USB power cord runs at... so if you plug a USB cable into your computer then mess with the other end (or a lightning cable for an Iphone) it's the same 5volts DC, just not enough there to break the resistance of your skin and shock you....

      Can you please give your opinion. I have a 1981 MsPacMan arcade console. It's getting old, should I disconnect the power when it's just standing there, or better to let it run. I worry about wearing out the picture tube ect. Thanks Teri

    What are you doing? You're supposed to be up against the clock because the customer is on the way right now, but the problem is still so elusive that you aren't sure you're going to make it (even if it really is an easy fix), and of course you're supposed to have arguments with co-workers and equipment breaking down. This is so anti-climactic. You'll never get that gig on Discovery at this rate.
