System V PowerPC ABI?

[Gerald Pfeifer]

Currently we have the following in readings.html

  <li><a href="http://www.esofta.com/softspecs.html">System V PowerPC 
  ABI</a></li>

but it seems the entire domain esofta.com vanished.

Does anybody happen to know a working URL? (If so, please go ahead and
fix this link.)

Thanks,
Gerald
