I ran into some of the same challenges removing the DIP ROM chips intact from my IIci motherboard. I have some Chip Quik and it's good for SMD removal, but based on tt's experience maybe it's just not useful for through hole stuff. Also, with the number of pins on the connector it's going to be tough to keep it molten on every pin with only a soldering iron. It stays molten for a long time, but not *that* long.
I also tried a solder sucker (spring-loaded) where I kept my iron on the joint while also holding the solder sucker over it and then pressing the button to release the spring, but it wouldn't suck up every remaining bit of solder, so the pin was still stuck to the through-hole.
Solder wick might work, but I had the same problem with it that I had with the sucker--it wouldn't remove all of the solder.
What finally worked for me was a vacuum desoldering gun. It's basically an iron that has a hollow tip you can put over the pin. Once the solder melts you pull the trigger, activating a pump that really does suck all the solder out (well, 99.9% of it). I found that wiggling the pin during this would help break connections to the hole. Unfortunately the Hakko 808 is about $180 so that might not be a worthwhile investment unless you're planning on doing a lot of connector removals...
I would guess that a hot air rework station could also do it if you go back and forth over all the pins until the connector just falls out. Maybe adding some Chip Quik into the mix with that approach would help?
