I keep having people tell me what architecture their specific systems are and, unfortunately, I usually end up smiling and knodding, hoping they think I know just what the hell they're talking about.
I've never been able to keep the difference between a sun4c and a sun4u separate in my head. Hopefully, the table below, taken from Appendix C of the Solaris Advanced Installation Guide (available via docs.sun.com) will help me keep them clear now.
