It surely was.

I used mine for about a year. Ended up in some user group, who set me up. Was a teen at the time. I did notice the difference, but not as much as I might have. Did not begin to get any typing skills, until much later.

Today, I actually enjoy the occassional time I get the machine out. That keyboard looks really cool, and the little click brings me impressions from earlier, simpler times.

Digging into my deep memories, I think I repurposed the 400 as a stand- alone MIDI application that didn't need keyboard input.

That seems like a great use case. Fun to think about.

It would have stage "presence" seen in some performance today.
