Ultrix-11

[Douglas Taylor]

Bill;

I started this thread by asking what I thought was a simple question 
about Ultrix-11.  Yes, I am trying to install and learn about this 
fascinating piece of old software.
Some of the folks who have posted know much more about Unix than I do 
and I am learning and enjoying this.

I just tried using the f77 compiler to see how it works.  It is really 
outdated and wouldn't recognize some accepted f77 items.  Even under 
SIMH it is slow!  But the load libraries are there.

There is a plot command in there that will drive a Tek 4014 graphics 
terminal.  Eager to find out how that works.

In the long run I would like to see if it can run on real pdp11 hardware 
and support multiple terminals/users.  Just for fun!

Doug
