1400i cpu cards

[pscowboy]

Considering the Thinkpad 1400i 2611-411, am I assuming correctly that its' SL34N cpu card was only made in a 300 MHz speed?
Were there ever faster cpu cards built? This thing isn't even labeled a Pentium II.

Do I have any options for improving the processing power?

lots of i series, I'm not looking it up this late but some were 390 based and could be upgraded, some were based on... well a 1400 and had the CPU solderd on the board a a 2621-460 (or was is 2611-460) comes to mind. I have a couple 1200i's here I haven't even botherd to take apart and one of the 500MHz celeron 1400i's. I just checked to see if they booted.
Is it Big with the CD and FDD on the right in one unit or is the FDD and CD on seperate sides?
