Ah, so that's your specification for an interesting system: weird with DECnet :-) The AS/400 is a nice choice then . 48 bit architecture, was supposed to replace the S/38 (it's code compatible with it) and be a VAX killer at the same time. Which obviously didn't work since every home has a VAX now as Johnny tells us repeatedly (or did I get something wrong ;-) Anyway, I've configured the IP stack on one of them, 10 years ago and what I remember is this. It follows the IBM way of doing things : nearly everything is menu driven. A system manager hardly ever types commands, he just fills in forms. The result ends up in a file which gets compiled or assembled with a bunch of others. AIX has something similar called SMIT (if my memry serves me well). Well, I prefer to type my own commands and DCL scripts. I'd like to get a small Unisys (n e Burroughs) A4 though.

Buy an RS/6000 - you can pick up a decent one for anywhere between 50GBP and 5000 GBP :D The RS/6000 is just a AIX / random Unix box, whereas the AS/400 is WEIRD. I like weird. Sampsa
