  Tymnet - Wikipedia, the free encyclopedia
Tymnet was extensively used by large companies to provide dial-up services for their employees who were "on the road", as well as a gateway for users to connect to large online services such as CompuServe or The Source.
Tymnet II was developed to ameliorate the problems outlined above by off-loading some of the work-load from the supervisor and providing greater flexibility in the network by putting more intelligence into the node code.
Tymnet II ran in parallel with the original network, which continued to run on the Varian machines until it was phased out over a period of several years.
