Hello,
I have found a copy of a very old version of AutoCAD (R12) for Win 3.1. Just out of curiosity I have started a Win 3.1 virtual machine that I had and installed it for testing purposes. It installed fine (amazing!), but the problem is that it has the "divide by zero" bug (I think it is c3 release), so it crashes on start. Does anybody know where can I find the c4 update patch files? They used to be in Autodesk's FTP (ftp.autodesk.com/ProdSupp/autocad/patches/r12c3-c4/c4win) but that FTP server is not active anymore. The technical support has told me that they do not support that version anymore (obviously) and they cannot help me.
Best regards.
