The central computer system at the Defence Research Telecommunications Establishment, Ottawa, is a Control Data 3200 with 32K of memory. In addition, several sub-sections within the Establishment have small computers which are used as part of the electronic instrumentation associated with their research projects. Problems encountered by some of the departments using these small machines, in particular the limited computation capability, led to the setting up of the Roll-In System, a limited remote access system which enables anyone of eight remote stations to gain access to the central computer on a priority interrupt basis.
