On a side note it just shows poor programming on Apple’s part . I mean they didn’t built it to last , at that point Moore law was very much in force , even few years ahead had they projected they would have clearly seen that 192 mb was going to be too less.

Most ofthe gnu utils still work perfectly fine many of them were written in late 70’s and 80’s , apple itself ships , in the latest OSX , posix utilities from late 80’s versions for GPL reasons.

Perhaps it is not fair comparison , utilities are not the same as an OS . unix or Linux from the same era may not work anymore as well.
