The DEC VAX 4000 Model 200 - Hardware Overview [Kind of English] 

Agreed. Your (DEC Computers) English is near perfect. You can relax...there's no need to worry if you're effectively communicating. With that said, awesome content from someone who worked with the Alpha/OSF side of DEC back in the day. Thank you!

Using something like this as a daily driver would be between completely impossible and very hard, depending on what you do. Or, what you would want to do, I should say, because a LOT of things most people do daily on a computer are no possible to do on this - at all, and a bunch of things can be done but in "ugly hack" ways so you probably wouldn't. But largely it depends on what kind of terminal you use and what software you have installed. If you use a VAXStation or a GUI 'terminal' as an interface you would be able to do most basic tasks with generic things on it without problem, like email etc, there are web browsers you can run, but a lot of them won't support modern XHTML pages and less yet will support modern features, plugins, scripts etc. But anyway, you'd really have to be 'hardcore' to try to use one of these things instead of a normal PC. You would have to have some modern PC next to it to do the things it can't, assuming you need to do the same kind of things most people do, or you might be able to do most of that sort of stuff with a smartphone - but you would need something else on top of having this. I mean for things like online banking, government websites you might need to log in on, buying things online, watching videos etc.

It would be nice to see more DEC content on RU-vid :)
