A NMR programmer is described which is built around a logic idea and a set of specifications, rather than availability of special or new integrated circuits. We begin by discussing what a quintessential Touring machine can do to solve the problem of outputting words (or pulses) with the resolution of the system clock over arbitrarily long time intervals. We then illustrate a simple realization of this machine, with 4096 program lines, 25‐ns resolution, two 16‐bit output lines, the possibility of nesting loops down to the 256th level, and a component cost in the 102$ range. A software ‘‘human’’ interface has been developed in an IBM‐PC compatible (MS‐DOS) environment, which simplifies the task of debugging the entire NMR spectrometer, and that of designing new experiments. While certainly overspecified for all traditional solid‐state NMR experiments, our programmer may meet the requirements of recently suggested selective excitation and imaging experiments in liquids.
