This depends on what you want to do. Any Pentium is good
enough for processing the output of a transceiver.

I do not know what performance a Pentium-II has in comparison
with a Pentium-MMX so I can not say how much bandwidth you will
be able to process.

A Pentium_MMX with 266 MHz can process two channels of 96 kHz
each (4 audio channels at 96 kHz) provided that the second fft 
is disabled and parameters optimised for speed. I had one at the
SSA meeting this weekend to show that the WSE converters can
be used with an obsolete computer to provide a really good HF 
receiver.

No problem.

Yes. Later versions are typically more efficient. There is a bug
reported by Graziano that 01-18 causes crashes due to segfaults.
I do not know what it means but it could indicate an error that
would make it better to use an older version right now.
