Before Truespace, Caligari published 3D software for the Amiga OS.  The program Caligari Broadcast saved objects in the .sobj format.  I have some objects in that format but can't find anything capable of converting them to .obj.  There was a bug in Truespace 1.0 that caused these objects to come in with offset axes.  I think it was fixed later, but I'm not sure where to get early versions of Truespace at this time, and if they still would work under Win7.  I had a program called PixelPro ages ago that could read the .obj format, but I've never been able to get it to run since leaving Win2K years ago.  Anyone have a suggestion for this unusual problem?
