Sometimes even on perfectly fine motherboards the cpu will conly come loose if you apply power to the lever when lifting up (after you moved it sideways a bit so it doesn't hit the lil plastic thingy).
Many Socket 3 sockets seem to work that way.

And anyway, since the mobo is toast, you might as well apply a bit of brute force 😜

Brute force always wins 🤣

I pulled out a CPU once without moving the lever 😜

That lever is really for girly men (Zero Insertion Force) 😁

I had this happen on several occasions when trying to remove only the heatsink. The heatsink would be stuck to the cpu by hardened cooling goo and pull the cpu right out, even though I tried twitching the heatsink a bit. Doesn't seem kill the mobo though, at least not at once.

Edit: On several occasions, when trying to remove a heatsink from a 486-era chip, it would eventually come off, taking a large bit of the print with it! -_-
Maybe those heatsinks with half the print on them (in mirror of course -_-) thus have some value to collectors also 🤣!

I think that applies to most people who've ever worked on a S478 or S754 system... concave IHS surface + flat heatsink + sticky thermal paste = aw, dammit. 😁

I did that at work with a 3GHz Xeon once 😳
No bent pins, still worked OK, but took a bit of effort to get the CPU off the bottom of the heatsink 😜

At work 🤣 that's funny...

nobody saw me do it so it was all good 😁

No one had this problem also with AM2 CPUs ? Happened to me some months ago. There was AS5 between the CPU and the standard AM2 cooler. The cooler didn't want to come loose, so I said 'to hell with it' and puller upwards: the CPU didn't offer much resistance, it came off nicely along with the cooler. No harm to either the mobo or CPU, but it was a pain later to remove the cooler from the CPU (flat knife + force=CPU - cooler) 😁.

Yeah, AM2/AM3 and S939 are pretty easy to yank loose too... same deal as with 478/603/604/754, the tiny pins just don't have a lot of area for a retaining mechanism to grab onto.

A little twisting to break loose the paste is the key. If possible. The AMD retention bracket makes this a little bit trickier.

Finally I've managed to remove it by putting some I-forgot-the-brand grease-in-an-aerosol-bottle to the ZIF lever. It has no heatsink nor thermal paste, so I have nothing to be the handle for grabbing the processor directly 😀

The motherboard looks pretty ironic. Most of the SIMM slots and headers are corroded, and some circuit lines are somehow scratched by a sharp object. It has Award BIOS chip, two IDE and floppy, and a whole lot of PCI and ISA slots. It has Dallas clock, which is really nice so you don't have to worry about flat CMOS batteries 😀

No instead you just have to worry about flat Dallas clock chips 🤣

those things are actually pretty annoying as they are only suppsoed to last 10 years, so any boards that have them are almost certainly flat by now. I have a few myself. It can be hard to track down replacement chips in working condition. Apparently you can hack at the top of the chip to fit a CR2038 button cell battery holder to them but it seems like a lot of screwing around.

Apparently there are NEW DS12887A+ chips. The date code on them shows they were made in 2009. Dunno if they are DS12887A compatible, I guess they are.
