Passage: Linux was, at that time, specifically built for the Intel 386, a significantly more powerful (and expensive) processor. Tanenbaum also specifically states "... as of about 1 year ago, there were two versions [of MINIX], one for the PC (360K diskettes) and one for the 286/386 (1.2M). The PC version was outselling the 286/386 version by 2 to 1." He noted that even though Linux was free, it wouldn't be a viable choice for his students, as they would not be able to afford the expensive hardware required to run it, and that MINIX could be used on "a regular 4.77 MHz PC with no hard disk." To this, Kevin Brown, another user of the Usenet group, replied that Tanenbaum should not complain about Linux's ties to the 386 architecture, as it was the result of a conscious choice rather than lack of knowledge about operating system design, stating "... an explicit design goal of Linux was to take advantage of the special features of the 386 architecture. So what exactly is your point? Different design goals get you different designs."

Question: How many versions of MIXIX were there?
