Commenting on suggestions that Chicago would not be out by next September (CI No 2,315), Microsoft Corp acknowledged that the main obstacle is to get it to run on personal computers with 4Mb of memory: spokesman Collins Hemingway said that current test versions of Chicago run applications 20% slower than the same programs on the Windows 3.1 system – We’re quite happy with where we are, he said, adding that the second developer’s release is being shipped now and a beta test version will be sent out to users in February or March; chairman Bill Gates told a Wall Street analyst that the product might ship in October, but the company has consistently set the end of calendar 1994 as its target.
