Hummingbird Communications Ltd, Markham, Ontario, will unveil a new version of its HCL-eXceed X Window server for MS-DOS personal computers that supports XGA graphics: it is $600. The firm has also added a local window manager – hwm – with Motif look and feel, to its other MS-DOS-to-Unix products, and has a new release of its HCL-eXceed/W X Window server for Microsoft Windows, which costs $550. Hummingbird says the market for MS-DOS X Window server products grew by more than 300%, to $15.04m – 58,022 units – in 1991. The firm claims it took 29% of all such 1991 unit sales, although UK firm VisionWare took 39% of the Windows segment of the market – and White Pine emerged as the leading independent Macintosh X-server supplier.
