Actually PGA soldered in, all of 168 pins. (!!)

And, I had to do hard way by hand with a WTCPS Weller 42W with medium
screwdriver (rounded edges type). Man, many hours.
Oh, I did to TP 700C to repair that seperated SMD joints and upgraded
my LTE 386s/20 w/ AMD 386SX 25mhz and oscillator and that was nearly
3 years ago.

Besides, I did many SMD swaps with that tools setup.

Honestly, didn't see or worked on T3400's so no idea, info anyone?
Did Tosh. released T3400 models with different CPU's in it?
