Are Pentium III's Being Phased Out?

I'm having a hell of a time locating a PIII 800MHz Slot 1. I want to upgrade from my 500MHz. The prices for the 800 are still around $165 delivered, which I think is high. But, what surprises me most is the general lack of availability of this model. Anyone have the scoop on this?
 
I see a slot one on pricewatch for $127. I also see socket PIII-800 100mhz processors which you can use the adapter board to go from socket to slot. I did that with a PIII-850, 100mhz about 8 months ago.
 
Ouch! So I'd better get one while I can, I guess. Why are the Slot 1's being tossed in the dumpster? Am I aleady obsolete?
 
I'd prefer to get the retail box model, if I can. Don't want to be messin' with heatsinks and fans, if I can help it. Although, if necessary, I will go that route. Now that you mentioned it, does using an adapter to go from socket to slot have any downside to it? Is it difficult?
 
No, you're not obsolete 🙂

CPUs went to Slot in order to move the L2 cache off of the motherboard, so it could run faster, almost in sync with the CPU clock. Now that L2 cache is integrated onto the CPU die, there is no need for the Slot's PCB which increases the cost of the CPU somewhat (moreso to make than sell I think).

edit- the Slot 1 Coppermines don't have the L2 cache on the PCB mind you, they're almost exactly like a FC-PGA on a sloket (the only difference is the core is actually flipped on the FC-PGA hence FlipChip).
 
Slot1 P3's have been being phased out for quite some time now and availability has already dropped significantly, and prices have increased.
You may find it cheaper just to buy a FCPGA P3 and an Slot1 to Socket370 adapter.

Using an adapter is quite easy, and with no real downsides at all besides the inconvenience of it.

In any case, I'd suggest you but soon if you intend to because it's very likely Intel may soon start limiting production of all Coppermine P3 varients within the near future.
 
Thanks, folks, for the info. Looks like the way to go is the with the Flip Chip model and the adapter. Time to do a little price hunting.
