Compute4cash developed later part of 2010 if it could be called a pool.
One of the early ones for me but not earliest ( I think )

Started mining there early 2011 and paid thrugh Paypal. Closed when Paypal started giving them the
evil eye. Memory fails me so don't remember much more, using 3870's and CPU's + early modified GUIMiner?
Google and see what you can find.
