Post your comments for Open Old PowerPoint Documents in PowerPoint 2007 here

Seeing OpenOffice.org can open PowerPoint files, will it also open legacy versions? (I don't have a file to test this on, either.)

Find a copy of the most recent version of PowerPoint that did support it (buy online, at ebay, find it in a thrift store, etc.). Use that to open the files, and upgrade them to that version. Repeat as necessary.

For #1, you can also install an old Windows XP, 98 or 95 Virtual PC, so that installing Office 2003 or 97 would not be a problem. From there keep upgrading as mentioned.

Once I had a similar problem in AutoCAD, worst was files were on floppies with who knows what format. Had to dig a very old CPU to solve it, once on a network, shared the folder, copied them and got them upgraded thankfully. Good luck!
