Development: 1980's
Until 1982, Nomad was available only on NCSS's proprietary time-sharing system VP/CSS. During this period, with a few exceptions, Nomad was used only by interactive time-sharing customers via pay-as-you-go dial-up access.
This changed, marking the start of a new era when Nomad was made available as a separate product under VM in 1982 and under MVS in 1983. It is still available today for the latest versions of z/VM and z/OS. In the late 1980s, Nomad’s presence expanded to the PC when PC Nomad was released to run under DOS.
