I just saw some ENIAC panels at the Computer History Museum in Mountain View, CA and I'm hoping to visit the Moore School of Engineering in Philadelphia soon to see the parts they have. Now I'll have to visit Oklahoma and see the restored portion they have. (I've also got cousins there, so that's another reason to go.) I'm a big fan of ENIAC and the other early computers. As for "first", I don't think any computer should be called out as the first, each of them contributed something to the machines we have today.
