Crystal Computing were one of the smaller software companies which produced games for home computers in the early 1980s. It was formed by Chris Clark and Graham Stafford who were both students in Manchester.
Crystal split after an evening of argument known later as 'the night of the long knives' with the key programmers leaving Crystal to set up another company (Chandrex Ltd) which traded under the name Design Design Software.
