Display Systems Electronic Equipment Equipment Standards Evaluation Criteria Input Output Devices Online Systems Performance Specifications Purchasing Telecommunications These summaries have been compiled to assist users in selecting terminals for use with the National Library of Medicine (NLM) on-line systems. The summaries describe the salient characteristics and approximate prices of a large number of hard copy and display devices. Many of the terminals listed may be modified by the addition of various options such as upper and lower case, printed interface, and magnetic tape cassette units. Prices quoted are basic costs, not including options. Preceding the descriptive information are four sections: factors to be kept in mind when selecting a terminal, definitions of terms used in this article, a schematic of various terminal interfaces to communication facilities, and the address of each supplier.
