Really, now, Lauren.  Grind your axe more quietly.  PC/IX is indeed a
full port of System III.  Accept no substitutes.

We've been using it here for a while (net sites "chub" and "alewife" are
PCs running PC/IX) and the performance is not bad.  The kernel is
functionally equivalent to the Vax's, i.e. it supports the same system
calls, but the details are quite different to make it work well on the
PC.  For example, it includes the contiguous read improvements that Steve
Zucker talked about at last year's Uniforum.

In case there is any doubt, it supports uucp and mail.  As distributed,
it supports Ven-Tel and Hayes autodialer modems, and it is easy to add
support for new dialers without source code, since it calls external
dialer-specific programs to dial.  The "connect" program (like "cu" but a
lot more convenient, and provided instead of cu) calls the same dialer
programs, so it also supports various dialers.
