First of all, I need to note that I am not a mac master. All my mac experience started with the imac I bought this year. This month, we had a task of developing Tcl/TK on different platforms, which prompted me to start using mac machines. The description here is to tell you that I am not interested in exploring some strange linux usage, but I am forced to do some strange things. In fact, I found that at least half of the linux distributions are desig

minimum hardware configuration requirements are 28MB memory guarantee core operation, the RAM memory guarantee system operation, the minimum CPU demand is I486DX, that is, the textbook mentioned in the antique Intel 80486.
