SUMMARY Digital computers may be interfaced to electron microscopes in a variety of ways to provide on‐line facilities for the acquisition, storage, processing and display of data. The data may be in the form of either images or spectra, the former necessitating a large amount of storage or memory space within the computer system. This has led to the development of special‐purpose digital memory systems, known as framestores, capable of holding one or more complete TV size images. Framestores can be used for both image acquisition and image display at normal TV frame rates. On‐line computer systems with, and without, framestores are being applied increasingly in scanning and conventional electron microscopy. The introduction of new computer technology, coupled with a reduction in costs, appears likely to accelerate this trend.
