My fix for Agnus :)

[Sandman]

Thought I would share a little project I did.

I am sure that many of us have unfortunately broken off a pin on one of are beloved custom chips some which are pretty hard to come by anymore.

I did recently and would like to share some photos of the fix I did.

I machined down until I barely touched the lead that was embedded and then carefully soldered a pin to it.

Works great now thank goodness.

Great work Sandman!  Your 3000 Motherboard looks really clean and orderly as well.

I broke a chip recently, now thanks to you I know how to repair it...

That's nice clean, precise work.  Good to see.

[curtis]

Very nice fix!

Only wish I had the necessary tools for a repair like that.

[yssing]

That is a brilliant fix

[Ral-Clan]

I assume you used a dremel tool to expose the contact?

Hi,

What a fix for Agnus, just drill into her and then pin her. Why didn't I think of that

On DIP chips, I've carved into the chip package with a sharp knife until a bit of the lead was exposed. Then, using a saw cut a fine groove into the lead and soldered a piece of copper wire into it. For a PLCC socket you need very good precision, so good job on this!

Very good! I recently broke a corner pin of an Agnus myself. Not completely off, but it's very, very loose. Got help soldering it so it's ok for now. But I might need to do a more permanent fix and it's good to see how you did it!

Wow!  If I tried something like that then I'd end up with a 6" hole striaght through the motherboard.

You better remove the circuit from the motherboard first to avoid damaging it. But to be honest, I damaged the pin while I removed the circuit. Shouldn't have touched it at all it seems...

[Zac67]

One more reason to invest in a proper chip-puller and stop prying with those screwdrivers...

[mrknight]

I did use a PLCC extractor. But it only lift the circuit at the corner. And it was really stuck. I think the tool and the socket could be better designed. Oh well...

I did the same thing with one of the ZIP chips for my bridgeboard. Those little blighters lose pins if you so much as look at them the wrong way. I just used a craft knife and (slowly) carved on down through the casing till I got to the metal for the missing pin (which was luckily on the corner). It wasn't a very firm joint but it did until I found a replacement RAM chip!

I agree.

I used a PLCC extractor to remove an Agnus, but it was so firmly in the socket that I could easily pick up the whole Amiga by it if I had wanted.  And when wiggling it gently to remove the chip, the whole motherboard would have flexed back and forth if I hadn't exerted pressure on it with my other hand.
