Nope, earlier PIII's aren't fast enough to draw long results. I know 550 and 600 MHz Katmai aren't. A 700 MHz Coppermine might just squeak in barely.
Generally I've found you need to be in the 1 GHz ballpark for the longs.

I have an old celeron coppermine 700Mhz. it doesnt do Einstein atm but when it did it could still easily do a long WU in around a day and a bit. these old workhorses still get results in they just take a while. the only project i wouldn't throw them at is climate prediction otherwise they make deadlines easily enough.
Agreed, and as I said even Katmai's are fully capable of meeting the deadline. In fact EAH isn't even really a tight deadline project for mine or Coppermines, so theoretically there's no reason to not send them long results.
Keep in mind though the cutoff is determined by the BM's, so if they made it much looser they might end up sending them to hosts where they are tight deadline.
OK, there is no doubt that Coppermine was a big step forward for the PIII and let it get away from the limitations of the Slot 1 versions. In fact the basic architecture of the chip was elegant enough that Intel revisited it to evolve into the Core series when Netburst flopped.
That being said, keep in mind Coppermines were produced with clock speeds ranging from 533 MHz to over 1 GHz (IIRC) and could be OC'ed well in excess of their rated speed for the most part. It's argueably one of the best designs to ever come out of Intels Think Tanks.
However, we have been talking about the earlier versions of the chip and how that relates to how EAH decides which hosts will get sent long results routinely, and not whether they (and Katmai's) can run them within the deadline or far less than that even.

Just out of interest: Aren't Intel's mobile cores (the Banias and the newer Dothan, so, the ones that are sold as Pentium/Celeron M or under the Centrino brand) based on the Coppermine design aswell, just adapted to mobile needs such as speed stepping and low power consumption? I think I heard something like that but I'm not quite sure...

Yep, that's true. I wasn't overly worried about deadlines, I just wondered whether a host like this would count as a slow host when there are so many AMD 64s and Core 2 Duos around...

You are right.
The Pentium M (Banias, Dothan) and Core Solo/Duo as well as the Core 2 Duo are all based on the late Pentium Pro and his descendants.
The architecture was ever enhanced until now with multimedia extensions and better caches as well as energy saving features.
That product was a great invention as it is still up to par with even fresher architectures (like the AMD Athlon 64) - or even better in some ways.

My 400 MHz Pentium II Deschutes is crunching Einstein, SETI and QMC complying with deadlines. I now have 2 Einstein pending credits, one because of a Pentium III still not finishing. But I had to abandon climateprediction.net and BBC. Can't do that.

Absolutely, and in it's current Core and Core 2 form, most likely has AMD pushing hard for the next generation of Athlon 64 and Opteron to get out the door. ;-)
Actually if you're looking to build some Hi Perf crunchers and the budget is low, there are some Desktop MB's which support Core processors. The prices aren't bargain basement, but are somewhat less than the Core 2 family, so it's something to consider since their performance is still pretty good, and a Core Duo T2400 only burns 31 watts flat out for example.

My coppermine handled them just fine. I think it took 90k seconds.
OK, there is no doubt that
