Funny?
Sometime in the very early eighties -make it twenty years ago- I set up =
an x86 system (don't ask me exactly what it was, but I remember that a =
few months later we had the server upgraded to a fantastic 10 MHz). You =
said RAM? Must have been all of 2 MB.
It consisted of one network server and at least a dozen workstations, =
running SCO Xenix. It helped run the administrative section of a health =
care company, from patient histories to bank accounts. I used the server =
as my main operating and developing station, running the first Informix =
IDE (text mode, no X Window yet).
So once I tried to test its limits. First I set up some heavy tasks on =
all of my twelve alternate consoles (Ctrl-F1 to Ctrl-F12). Then, on one =
of them, from my Bourne shell (ancestor of bash, meaning 'Bourne-again =
shell') I ran the IDE. From the IDE I shelled out to a second shell. =
>From that second shell I opened a new instance of the IDE, and .. you =
got the idea. It didn't even flicker. The priting tasks went on, =
compilations took maybe ten percent longer than usual, and so on.
And all twelve running workstations on the network never noticed...

Thats funny,
=20
25 years before your >>8k. system handled 24 concurrent users<< today =
this WINDOWS-System with 200 MB RAM has trouble handling ONE user 
.
So what will be in 25 years ? We will have multiple Systems each one =
with 24 Processors and they will not be enough for 1 user ...
=20
Another out-of-topic thing: The Computers needed 25 years to rech the =
first GHz (1 GHz-PC).
The next GHz will be in range in 1 Year.

Have fun
