What CPU/Processors fit into the Sony Vaio PCG-TR3A for upgrade???

Recently I've been reviving my SONY TR3A, but with the old Toshiba 50pin HDD, it's been running realllly really slow and making kind of like clicking noises. But recently I have purchased a new 128gb SSD for it, currently awaiting for it by mail.

Since I could upgrade the HDD to a SSD, I was wondering if I could upgrade the Processor. It's currently running on INTEL PENTIUM M processor 1GHz. I've been looking all over the web to find a new cpu/processor, but found no real answer. I don't even know the size, socket, and it's compatibility. I hope someone can help me with this subject/project.
