775 mutton dressed up as 478 lamb?

I was sorting through my junk box, and noticed one the Pentium 4 CPUs
had on it 2M cache. I thought this must be the last of the socket 478
line, so looked ut up at Intel website. It is spec SL7Z9. However,
their webpage says is LGA775. I know there were a few models that
were issued in both 478 and 775 package, so I guess this is a mistake
by the webmaster, rather than me having a rare sample?
