The Model 100 is the old style unit with the black and white metal case and the backplane under the monitor. These originally came with Sun-1 processors, but can be upgraded to be Sun-2's. The Model 120 is the new style with the grey plastic case and the backplane in a separate box. Model 120's all have Sun-2 processors. Around here we talk about the Sun-1/100, the Sun-2/100, and the Sun-2/120 to make the distinction clear. (We'll ignore the 150 and 170 for now.) At any rate, 4.2 Unix runs only on Sun-2 processors, and definitely not on Sun-1's. (To further confuse the issue, there were some "Sun-1.5" processors shipped which ran 4.1c Unix. These should all have been upgraded to Sun-2's by this time.) --Tim
