The original "CMS" (Cambridge Monitor System) of CP-67 could run on a "bare" machine, and this was used to do the initial "SYSGEN" of CP-67, e.g. to specify the I/O configuration etc. to install CP-67 on an IBM S/360 model 67.
By the time VM/370 became available in late 1972 or early 1973, the VM version of "CMS" (Conversational Monitor System) could no longer run on any "bare" machine as it relied on a number of CP services provided via the DIAGnose instruction (aka. the "hypervisor call" in today's lingo.) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
