For instance, a version of UNIX that runs on P-E hardware. They need to make their hardware cost/performance competitive with other 32-bit vendors offering UNIX; nothing new in that. > P-E has strengths in the defense industry. > This means FORTRAN.

A good first step is the adoption of UNIX System V, which has better IPC support for real-time applications than 4.2BSD. > What of the business-oriented community? This is where it gets > strange.

The academic community happens to be using 4.nBSD more than AT&T USG/UDL UNIX for historical reasons. Vendors also have to look at future directions. Indeed, once Berkeley and AT&T straighten out the licensing issue, there is no good reason why the two variants should not come to look more alike from the applications standpoint. The big lack in UNIX System V `a la AT&T right now is decent network support. Some software houses have developed TCP/IP and network device drivers for their UNIX System V offering; P-E is advised to do the same. > How many folks running pure Bell UNIX out there > write your application programs in FORTRAN? I venture to say that most major scientific computation is still Fortran-based, UNIX or no. Is LINPACK available in C? EISPACK? IMSL?
