    Who Here Fixes Ms Pacs

    Which is still a good thing to experience. Someone who wants to repair their own boards should know how to fix their screwups (both troubleshooting and bodge work). It is incredibly valuable to learn how to do this kind of work. It also keeps ya humble. I work on boards just about every other...

    Favorite Controller

    I really like the yoke on Midway Space Encounters. If the encoders on that is solid, it plays great. Even if they aren't the best it is still solid. I am also a huge fan of the tempest spinner. It is just so fluid with the movement. I think my least favorite right now is probably my sinistar...

    The bottom of the machine was covered in dirt. I still have to do a better job cleaning this but I was itching to get it working.

    What fixed your game today / general repair log

    It was one of my requirements for a bench setup, I made it using a lot of piece of scrap material I had in the garage. Eventually I wanna make an actual sheet metal enclosure, but that is a down the road project...

    I sure hope not. I have no idea what it was. One thing I noticed on this board is that there are a couple spots with corrosion. Not sure if it was bugs or mice or whatever. I spent a lot of time cleaning this cabinet... I've cleaned it off since there hasn't really been anything severe. This...

    What fixed your game today / general repair log

    Game: Sega Head On 2 (Slimline/VIC Dual PCB) Symptoms: Accelerator button always pushed in Troubleshooting Steps: This was a pretty straight forward repair. When troubleshooting input stuff like this, you will usually have one of 3 failure points: Cold solder joints on the pin headers/harness...

    The Gorgar pinball used the same sound and speech board. I figured it would be funny to put that because they are both hungry.

    I think you nailed it. I piggybacked one and it ran a whole hour without crashing. As soon as I pulled it, next time it went into gameplay it crashed. I went ahead and swapped the 74ls373 at 3H and am gonna let it run for a while. I also put a fun message on the title screen, it's neat that I...

    Nothing serious. Little bit of green on the holder solder points and the holder was trashed. I made myself a remote battery pack to keep em off the board from now on.

    That could make sense. I didn't consider it because I figured I'd have more problems being it is with the dram. But I suppose the occasional miss with latching would cause problems. I'll take a peek after work today. Thanks.

    Managed to get this exactly once. Odd that the background was yellow for this. Sometimes if I run the RAM test, through the coin door buttons it will say ram 21 or 22 (they are both new), once it said 24.

    Here's what I tried this evening: Replaced the sockets for the decoders and CPU, those were a bit yucky. No change. Burnt a new ROM set for the off chance something goofing around. No change. I am going to start poking around tomorrow, I'm gonna start by poking the 153s, I've had terrible luck...

    Post-capkit Sanyo 20EZ width issue

    See how it looks in the game. Tpg can give you a "false alignment" as its timings are different than the game. Sanyo 20EZs can be a headache with this alignment stuff. Games like donkey kong which would have used a 20EZ have position adjustments on the game board. I typically do calibration...

    Post-capkit Sanyo 20EZ width issue

    A couple things: make sure you are hooked up to *negative* sync, looks like you might be hooked up to positive sync. Check that first. Otherwise, try asjusting horizontal hold. Sometimes when it isn't locking correcrly it might do that.

    Solved (I think) - Sinistar Freezes During Title Screen and Gameplay

    Switch test passes yes, it's goofy sometimes as the cable on my widget board is pretty flakey. I didn't think to run the sound tests because I could hear the sounds and all that. Although earlier it played the starting music inbetween lives 2 and 3, so maybe there is something there. The game...
