IBM AS400?

[9000 VAX]

>      BIG GOTCHA- you need to make sure your machine comes with not only the OS, but also the mashine-specific intermediate layer software. Unless you have a friend at IBM, they may be happy to give you a replacement in return for much cash, or they may do the snooty Maitre d' thing . . . and OS/400 is rumored to lock itself after a certain period of inactivity as well.

You have found the reason why there are so many DEC fans and no IBM
fans on the mailing list.
