Since we are not part of the Bell System I have a question for any
Bell/AT&T employee out there in net land. There have been many references
of late to versions 4 and 5 of UNIX*. The last BSTJ contained an
article that referenced version 4.0. Now I see references to 5.0 too.
>From what I understand, versions 6 and 7 were actually 1.6 and 1.7;
version 2 never made it out the door to sites other than Bell;
version 3.0 is now being sold by AT&T (System III).
What are versions 4 & 5 ? What has changed from V7 and System III ?
I hear rumors of inter-process communications and real-time ?
Has Bell finished using version 3 in-house ?
Please mail me directly, rather than multiple answers to the net.
I'll summarize if there is interest.
