To add to this: piggybacking is best used when you already suspect a chip to be bad (for example if you see it's outputs looking really wonky on a scope). With logic chips it is about seeing positive change. In my experience it almost never makes an issue disappear.piggybacking does work, but not for everything
It's okay. Vector Collector and I have very dry humor. You are fine.I don't understand.
I don't know if @HudsonArcade thinks people are piggybacking chips and soldering them on that way to fix the problem or what. to his credit, in that scenario, that is idiotic.To add to this: piggybacking is best used when you already suspect a chip to be bad (for example if you see it's outputs looking really wonky on a scope).

It's more of a curiosity thing, not an idiot thing.
I absolutely did my friend. and this pic is what I found. GG-2 Prom was my staring point. I believe I mentioned this in my 1st post. Finding out what comprises this prom is where I got off the path. So I try other options in an attempt to track down the chip and any such requirements in the hopes of replacing it. I can assure you I didn't come here on day 1 or even day 10. Attempts to get more information about that particular prom probably caused me to misinterpret what I was reading. Not sure how much more information you'd like from me to explain why I made a mistake (If I knew that I guess I wouldn't be asking for help would I???).. Or you could offer help instead of highlighting my errors. I came here in the hopes of clearing that up instead its feeling as if Im being heckled for being a newbie. So unless we can get past this shaming part. I think this conversation is over and I'll seek expertise elsewhere.Why the hell are you looking at some text file instead of the PDF.

That "works" for exactly one type of failure -- an open output driver.if you suspect a chip to be bad and you piggyback a working/new one on top and it either clears up the issue entirely or in the least influences something else, then you've confirmed the chip is probably bad. you can save time this way, and I know this for fact this works because I've actually fixed games using this exact method.
Since you're still too dumb to get it -- I diagnose by looking at the display and knowing how the board actually works. It really doesn't take much time.sit around with an oscilloscope to figure out exactly why the address bits are quarreling and have disagreements and won't function properly.
You don't get to tell me how to spend my time, kiddo.you should probably use more of your time trying to actually help people like I've seen you rarely do
You could read and learn and start doing things right, but that's just not your style.than shit talk and motherfuck them about how stupid they are and are doing everything wrong.

unfortunately I'm not as cool as Mark Spaeth and don't know how address bits mate and I do more things and fix significantly more games on the daily to sit around with an oscilloscope to figure out exactly why the address bits are quarreling and have disagreements and won't function properly. you should probably use more of your time trying to actually help people like I've seen you rarely do than shit talk and motherfuck them about how stupid they are and are doing everything wrong.


All good brother. Friend of mine has about 16 machines His favorite is Omega Race . I personally admire his star wars machine. All of that is to say. he has a LOT of respect for any and all folks who repair vector games. !!! He stated its on a whole other level of difficulty.It's okay. Vector Collector and I have very dry humor. You are fine.
this is why @gamefixer is the GOAT@sheister. I've fixed bad audio on that board by replacing the PROM that you mentioned a few times in the past. PM me, I have a bit of advice that can help.
@HudsonArcade. Why do you have to come into these threads and be such an asshole? This admitted newbie came here for help, not a fucking tongue lashing. Good lord, man. I've said it to you in the past, and I will keep saying it: you are a smart guy. Why not be nice to people here and not jump down their throats? What effect will it have on YOU if someone gives advice that isnt spot on? Why do you let it trigger you?
And piggybacking... I find that it works a lot more than it doesn't work, and when you KNOW how a board works, it also helps to quickly troubleshoot the problem. Seems to me that a lot of IC failures are in fact open gates, and thats why piggybacking works more often than not. Now, in the case of a shorted output or input, piggybacking isn't going to do a damn thing. RAM, on the other hand. Piggybacking works A LOT on them.
I dont know man... I dont understand why you come here and stay here if you think so lowly of the rest of us.
Seriously, Mark, chill out.
FYI no kiddos were hurt during the course of this messageI wish Mark would stick to being helpful and not nasty towards us. It's so strange to me that someone so damn smart can be so stupid at the same time.
I'm not saying that he shouldn't defend himself when someone shits on him, but it's usually him doing the shitting first.

Please don't bait the trolls.I'm sure a kiddo is forthcoming. lol
Maybe he will look at the man in the mirror? Who knows.
MY BAD!Please don't bait the trolls.
Thank you.
I will contact you soon.@sheister. I've fixed bad audio on that board by replacing the PROM that you mentioned a few times in the past. PM me, I have a bit of advice that can help.
