Carefully.

I got an old 486 chip removal tool (pin spacing is the same) but they're harder to find lately.

Indeed. But what if you don't have that elusive tool?
I'm trying like crazy with thin pieces of galvanized steel wire slipped between the chip and the socket, and it feels like it hasn't moved a single micron.
I sincerely hate this Rocket Stage II, but not enough to want to break it in half.

Maybe I'm exaggerating my hatred for the Rocket Stage II, but I've never had the slightest trouble removing a 68040 from a motherboard with a little care and standard tools. I don't know what kind of damn socket Radius used here, but it really bugs me.

Something wide and thin like a paint scraper to spread the force as widely as possible. Those sockets seem to stick. The other thought is - do you really need to remove it? If it's stuck, don't risk it.

You're absolutely right. It's not worth the trouble. I got caught up in the challenge and the determination to remove the CPU at all costs.
I actually use a paint knife most of the time; it’s always worked well on standard sockets.
I thought I could easily remove the CPU from this board because I didn't want to open the case of one of my Quadra 840av and have it fall apart even more.
The ultimate goal is to finally check out a QuadDoubler clone that I bought from Bolle a while back.
