Opened up my MV2F to give it a little cleaning today and saw this: I got no idea how that got there, I've had this board since maybe late 2001? Been using it regularly since then, and I never noticed this. I did consolize this back in 2001-02 and swapped in a coin cell holder a few years later, but I wouldn't have soldered those pins together like that, even by accident. The board has been working perfectly with 0 issues for almost 20 years now, so it's seemingly not hurting anything... but I have no idea who did that and why. Is that some kind of old mod or repair I'm not aware of? |

That looks like an unintentional solder drip. The middle pin is connected, but the ones on either side don't have any trace leading to them, so those aren't intended to be used. They might be getting a signal fed into them, but if it's having no ill effect, don't worry about it. Have you tried just gently scratching it off with your fingernail? Drips/splashes usually aren't very strong. |
| snappleman:
Yeah I tried scratching at it, it doesn't budge. What I also see when looking real close is what looks like a bar of solder in there, so it's definitely a drip someone got on it while tinning an iron. I'll just clean it up by soldering it off, but then watch the board inexplicably stop working :D |

Be ready to open up a can of worms when you "fix" a board that is working fine. If I had a vote in this matter it would be "no". The board has been solid for 20 years of regular use. Just pretend you never saw that glob. |

That looks like more than a drip of solder to me. If I told you to bridge all 4 of those pins and connect to that via you'd find out it takes a bit of work to tie that all together. |
