Hi Dave, yes I have an old O2 computer with the amazing irix 6.5.22 operating system. At my first IT job these machines were still used for oil pipe design (along with some other SGI machine, eg. Indigo, Octan and Indy) and when they were scrapped I couldn't resist the temptation to buy a few (Indy and O2). The last still working Indy is now in the attic, but I still use an O2 in my carpentry workshop for listening to music :-)
