Saying that it did not have time to implement the System V Interface Definition for its implementation of Unix, DEC was a no-show when the bidding for the $4,500m contract for 20,000 small Unix systems for the US Air Force closed the second time around on December 22. DEC and Wang originally got the deadline extended by protesting that the contract demanded standards that were developed and owned by AT&T and therefore gave the company an unfair advantage, but appeared to be mollified by the ruling on its complaint. AT&T acknowledged that it bid, but Computer Systems News could not find any others who put in bids, although Unisys and IBM and perhaps Wang were likely.
