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

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

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 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.

Back when I routinely fixed A500s (those golden times... ;)) I had a plate with screws fitting into the PCB holes - just put the board on the plate, push it down and send Agnus popping out.


Ah!  I wondered if those holes could be used to push the chip out.  I almost tried to push the chip out that way, but after it started to look like it was going to take quite a bit of pressure I got scared and ordered a PLCC puller online.
