It is 478pin with 400mhz bus and 512kb cache. As for upgrades, you would probably have to contact toshiba support and ask them. They don't provide documentation publicy on cpu upgrades. However, I did notice one of the BIOS updates mentioned support for "Dothan B1 step" cpu's, so theoretically you could get one of the 1.7ghz cpu's with 2mb cache. Those will run you under $50 on eBay. It would be a noticable speed upgrade for a laptop/tablet, but carries the standard risks associated with upgrading cpu's on mobile devices. The cooling system may not be capable of handling a faster, hotter cpu...

Thanks, that seems to fit in with some bits and pieces I've been able to find on this subject.

According to Toshiba support, the M200 model has the Pentium M 735 (1.70GHz),and the Pentium M 745 (1.80GHz)
as the M205 has the Pentium M 1.50GHz.
Since Toshiba gives all of these models with the same specs other than the CPU's, I would guess they all have the same motherboard and can be interchanged.

The only issue could be, the Pentium M 1.5GHz in your laptop now, has a 1Mb cache rather than the 2Mb as it's not identified by an Intel number like the 735 and 745.
You can run  the intel processor finder to find the specs on it
