You are right. According to Sun, there are no restrictions. Back in the Solaris 8 days (last one I downloaded for my SPARCstation LX), you had to pay for Solaris if running it on more than 8 CPUs.

I just discovered that my Compaq Evo N600C (a freebie currrently running Kubuntu) will run Solaris 9 and 10. Hmm....

Peace,
