As for software:

Word 5.1 (Save as RTF with extension .rtf)

MacPaint

Excel 1.5 (still compatible with even Excel 2003, save as SYLK with extension .slk)

But you are going nowhere unless you get an HD floppy drive, or better, a zip drive. Kind souls on this forum will probably donate a 800k disk with Zip software. Then again, though, you will be at a disadvantage unless you run Linux or Mac OS.

Good luck and sweet haul, Mac Plus machine are awesome.
