There exists a Coppermine Celeron that is PPGA compatible. I think it is early revision of 566 (probably SL3**). It would work in PPGA only motherboards. It should be very cheap as it's the slowest Coppermine Celeron and few people know that it is PPGA compatible. See Re: Celeron, the good bad and ugly.

I had Coppermine Celeron 566 SL4PC but don't remember if it worked in PPGA socket.

It seems you need SL3W7 or SL46T. See Related S-Spec numbers in https://www.cpu-world.com/sspec/SL/SL4PC.html

Thank you for the information, I'll look for those and see what I can find. I don't know why, but CPUworld banned my IP and I have not been on that page for years until recently when I started building my Windows98 machine.
