Close! Costco is 5250, which has many similarities.

They are a very famous AS/400 shop.

Heh, up until a few years ago our inventory system ran on an AS/400, and we had to use 5250 emulators to log in. Don't miss it.

The problem wasn't the AS/400 (IBM i) it was the 5250 interface. That's throwing the baby out with the bath water.

And even then, as with any other UI model, application design plays a massive role.

A lot of gas companies are too, especially on the distribution side. Actually AS/400, and VMS. And very recently.

VMS is very good for high-availability systems.
