(There's no video for WebObjects 4.0.1 yet. Please contribute to MR and add a video now!)
For Apple Rhapsody, or OS X Server 1.0-1.2 v3, this image represents the developer tools for this OS. I created the toast image using Toast Titanium v10 under OS X El Capitan. If there is some issue, please let me know and I'll try another method. In addition to Web Objects itself, it installs the rest of the development tools (cc, ld, etc...) as well as Project Builder and Interface Builder most closely representing the OpenStep versions. From what I can gather, this is the version of developer tools that shipped with OS X Server 1.x with 1.2 v3 sometimes shipping with a 4.5 version.
The serial number for the Web Objects portion is B-321-UFD-162-QCO-357-GSB-357-CXC-340.
This bit of software should be hosted or at least linked to on the Apple Rhapsody (Intel and PowerPC) page. It should also be noted that finding a copy of this disc has taken me weeks of continual research. Please share and mirror.

This is for the Copland look and feel version of OS X Server. Also know as Apple Rhapsody. There appears to be Intel binaries on the disc as well. You may need to burn the data to disc as it does not directly mount in OS X. It should appear and be mountable in OS 8.6 - OS 9.2.2 as well as OS X Server 1.0 - 1.2v3, of course.
Emulating this? It should run fine under: SheepShaver
