The rebel group of multi-national Unix user companies that clubbed together after the breakdown of the Unix International/Open Software Foundation Unity talks is currently operating under the name of Houston 30, after the place and time – May 30 – of its last meeting, although there is some disagreement about this because Computerwoche reckons it represents the number of DP managers present. The members – Du Pont Co, Ford Motor, General Motors, Hughes Aircraft, McDonnell-Douglas and the US National Aeronautics & Space Administration amongst them – have voted to adopt the model of the Corporation for Open Systems as the basis for its organisation, though it does not plan to join or merge with Corporation. A working group is preparing a report on how to overcome the problems thwarting the drive to open systems – set for August – and a follow-up meeting is to be held in Detroit. Unlike the similar, but more outspoken rebel oilmen’s group the Petrotechnical Open Software Corporation, Houston 30 is not so clear about its practical plans and methods. Although Houston 30 – an amalgam of hardware and software manufacturers, communications and engineering firms – lack the common basis that the oil firms share, Bud Huber of Hughes Aircraft, and spokesman for the Houston 30, reckons that the underlying features of the systems that they want are common across all industries.
