The CRISTEP desktop plotter system for molecular and crystallographic drawings

A program system is described whereby high-quality drawings of crystal and molecular structures may be prepared with relatively modest hardware, such as a desktop plotter driven by a similar computer or minicomputer. It is written in Basic and consists of a suite of six overlay programs, each performing a specific task in the process of setting up and executing a drawing. The mode of operation is fully interactive, through features such as console prompting, provision of preview plotting and immediately accessible correction or editing facilities. The system is easy to use, even for inexperienced users, and demands the minimum of time and effort on the part of the user.
