       Well, that #BlueChip drive CPU was a right pain to get out. Had difficulties sucking through the solder from the top layer. But after 2 rounds of resoldering/desoldering all the pins, I was finally able to pull the 6502 out - and it looks like I didn't damage any pads or tracks in the process. 😅​And yes, this is one dead CPU.#retrocomputing #repair

       @Retrograde if the chip is bad, you can also cut all the legs beforehand and then desolder them one by one much more easily

       @piggo The CPU was suspect, not proven bad until it was out.But either way, I do not actually recommend the leg-cutting method except as a last resort.1) I find that it's actually a lot more work because you have to snip, then work simultaneously - pin after pin - on both sides of the board (pliers on one side, soldering iron on the other), in an awkward position.2) I find that it's easy to damage the board or lift pads when cutting, because the sidecutters put a force on the leg when cutting it.YMMV.

       @Retrograde good points. I think I only did that for smaller packages, so it wasn't so much work, this is a monster. I'm surprised you even dug it out without ruining the board
