This paper explores an episode in the development of instrumentation in modern astronomy. It describes how five groups of researchers embarked on the process of uesigning and building infrared cameras incorporating 58 x 62 element InSb mosaic arrays, and reports on the situation reached by mid-1986. These detector arrays were originally manufactured for military purposes, but were made available to a wider market in the early 1980s. Several astronomers realised their potential, and engaged in something of a 'race' to exploit it. However, their aims were different, and the resulting `competition' was complex. A range of factors led to a variety of designs, with each group giving its own instrument a distinctive 'signature'. The paper investigates the origins of this variety.
