It could be a Athlon with a Tbird core, but it's just as likely to be a
Athlon XP with a Palomino, Thoroughbred, Barton, or Thorton core; well,
at least a Palomino core. But, call it what you will, I believe I said
that it will run at 1333 MHz at 266 MHz FSB. Let me check....yeah,
that's what I said.
The Athlon series ended with the Thundrbird core that ran at 1.4 GHz
max. The Athlon XP series started with a Palomino core running at 1333
MHz, the XP-1500+ and was the first and slowest Athlon XP CPU.

Iconoclastical, it's all come back now that I found a site with info
regarding the different cores, L2 cache size and speeds. What you need
to get from the seller is the Identification numbers on the CPU. It
will consist of numbers and letters, each of which is explained here for
the Athlon XP family:
http://www.cpu-world.com/info/id/AMD-K7-identification.html#Athlon_XP
An Athlon XP 1500+ with a Palomino core, for example, will be identified
this way: AX 1500 DMT3C. If any of the letters or numbers are
different, look it up in the chart.
If it is an older Athlon CPU with a Thunderbird core, then this chart
should be used:
http://www.cpu-world.com/info/AMD/AMD_Athlon.html
Near the bottom is the ID for the plain Athlon CPU, Thunderbird core at
the same speed:
A1333AMS3C (perhaps that's where the seller got the "C").
Make sure what core it is, as they each have different voltage and
current needs, and you'll need to confirm that your motherboard (and
PSU) can supply what it needs and that the BIOS can provide the proper
multiplier.
This link explains the difference between the differently named Athlon
XP cores.
A bit further down, it has pictures of the CPUs along with the ID number
on the left side and a short list of it's features (in most cases).
This should be all you'll need. If the seller doesn't (or can't, or
won't) give you a full ID number, don't buy it. You'll not know exactly
what it is.
