Yep, I remember those. I didn’t have an eMachines though. Mine were both HP, I think. I had something called a Superdisk drive in the first one. It was before CD drives and it was a 3.5 inch disk with a lot more capacity than a regular disk. It was also the memory media for my first digital camera. The second one had the CD and the standard 3.5 disk drive, and I had a separate external Superdisk drive. After that, I went to laptops, of which I am on my fourth.
I particularly like that the eMachines claims to never become obsolete . . .
