You would have to get the flash drive kit for the 2000

It's a large unit but much faster when compared to loading files off of a zip drive.
There is also the option of installing a USB floppy emulator:

Sounds nice until you realize that it can only save and load 1.44mb of data like the normal floppy disk. Thus, the name floppy emulator.
On my 2000 I use the flash drive kit.
