PowerBook 1400cs and CPU Upgrade
I have a PowerBook 1400CS with a Processor PowerPC 603e. I've read on some threads in the Net I can upgrade CPU with a G3 266MHz. Is it true?
PowerBook 1400 CS - 64 MB Ram - HDD Transcend CF 8GB

There are G3 upgrades available for the 1400, they were made by NewerTech, VImage and Sonnet. Very hard to find though, and very expensive when they come up for sale.

Just buy a Kanga instead.

Easier said than done. 
Next step up from a 1400 is a PDQ. I've never had much love for the 3400 form factor.
