The application of an ultrafast analogue-to-digital converter and a high-performance-single board microcomputer permits the construction of a very fast and versatile multichannel analyser (MCA) at low cost. With the powerful instruction set of the microprocessor MC 68000, an intelligent all-round MCA could be realised with useful correction software on the single-board microcomputer. This MCA was used successfully for a data collection by Laue techniques with a four-circle diffractometer.
