If there appears to have been a sufficiency of Tempests swirling around the industry this week – and we’re not talking about this rotten summer in Northern Europe – the explanation is that the 41st Annual Armed Forces Communications & Electronics Exposition has been going on in Washington: pick of the crop are perhaps the Data General offerings – the Eclipse MV/15000R Rugged and MV/15000T Tempest series – claimed to be the most powerful Tempests yet, capable of more than 6 MIPS in their top model, they come in three configurations, Model 8, Model 10 and Model 20, ranging from 2.9 MIPS to 6.4 MIPS and from $117,500 to $284,000 for the Rugged version, from $177,000 to $299,000 for the Tempest version; field upgrades involve swapping one board and loading new microcoded instructions; Data General also introduced a new Tempest Dasher D461T VDU.
