As an untrained 'intern' I managed to install Solaris on an Ultra 10 that the company I was contracted to help somehow never managed. Later I got to keep it. Ditto a Sun Enterprise 450.
Neat! I worked at a big Sun shop for a while, one of my first jobs out of college. We had Ultra 5 and 10's on the desktop, E450's and E3500's for servers, various huge fiber channel attached storage arrays, etc. I really loved Sun hardware. Too bad they were absorbed by Oracle.
