opencyc-backups

Backups for old OpenCyc distributions. Some projects rely on old OpenCyc distributions, and the main opencyc project sometimes deletes them at end of life. So, they will be stored here as an eternal storage.

MD5 Checksum---->opencyc-4.0-windows.zip----> ab58a03cce6cfeae4756da04ced8a5a7 ----- I have been following the Cyc project since 1990. I was able to get this OpenCyc system to run on [Windows 7 Professional 64 bit] on VirtualBox 7.0 yesterday. Numerous tests were made proving that the system functions correctly. Various LLM systems assure me that this 2012 system is fully programmable with the Cyc Project's SubL version of Lisp and the CycL language. I have spent 28 years formulating the infrastructure to make "true on the basis of meaning expressed in language" reliably computable for the entire body of knowledge. I just completed the outline of the architecture a few weeks ago. I intend to implement working examples of this in OpenCyc. My system eliminates undecidability by replacing inferential foundations.
