The first IBM virtual machine operating system was implemented on a specially built 360/40 with a CAT (Cambridge Address Translator... equivalent to a TLB). That was in 1965. A few years later, IBM introduced the 360/67. There was an official operating system named TSS and a renegade named CP/67. From whence derived VM/370.VM has been available on most IBM mainframes up to the current day. So, it even predates Unix by a 4-5 years.
