IBM System/360 Model 67
- greenyoda 11y agoNot only did this machine have virtual memory, but it ran a virtual machine operating system, in 1967: https://en.wikipedia.org/wiki/CP-67 https://en.wikipedia.org/wiki/CP-67 https://en.wikipedia.org/wiki/History_of_CP/CMS#1967.E2.80.9368:_CP-67 https://en.wikipedia.org/wiki/History_of_CP/CMS#1967.E2.80.9... The second reference above has an interesting tidbit: At the time of the S/360-67, software was "bundled" into computer hardware purchases... In particular, IBM operating systems were available without additional charge to IBM customers. CP/CMS was unusual in that it was delivered as unsupported Type-III software in source code form – meaning that CP/CMS sites ran an unsupported operating system. The need for self-support and community support helped lead to the creation of a strong S/360-67 and CP/CMS user communities, precursors to the open source movement.
