Some slotkets for Coppermine can run a Tualatin straightforward, provided some CPU pins are modified. My DIY pin-modified Tualatin 1400S on a MSI-6905 v2.0 slotket works like a charm. But modding the CPU is a hairy job. There's a Korean guy who sells already modified Tualatins, ready for plug & play on said slotkets: http://www.ebay.com/itm/Tualatin-P-IIIs-1-4GHz-512K-include-Socket-Adapter-/281238323137 Not really worth the trouble nowadays, except for some crazy retrocomp enthusiasts.
