Up to System V R3.2, there are still some difference between different 386 unices. So be careful! If you buy R4, I would say you will be in very good shape. R4 is bascially the same thing as SUN OS 4.1 (90+% compatible?) and as it is from AT&T is a fairly complete package so different UNIX vendors won't be (except SCO) contaminate it very much. I would like to say that depending how much time you can afford, nowadys with these very stable software developement packages gcc/gdb/g++/bison/perl ...., you never need to pay anything other than your time. You get src too! Regards, Chin Fang Mechanical Engineering Department Stanford University fangchin@portia.stanford.edu
