Dupont de Nemours et. ci. in WIlmington, DE. Among other things, it ran "the Freon simulation", which evidently helped make up Dupont's mind on the ozone. Ours had a drum memory. The drum was about 20 feet long, two per cabinet, moving them required creating a hole in the side of the building and moving them with a crane. I once slipped while emptying the card reader and hit about 30 switches at once with my upper arm. The machine locked up. That's where I learned an important lesson: figure out if anyone saw you, walk away slowly, make no eye contact, "must be that software bug again" ... works every time. > Bloody marvellous, it was.

Hm, maybe I should look for a simulator for > it, anyone know of one? That would be fun, but you'd have to find Exec 8, right? Ah, the days of lights and switches. Today's machines have no soul. ron
