Fremont, California-based Opus Systems Inc has simplified its software for accessing SparcWare applications from MS-DOS, Windows and OS/2 powered personal computers. Incognito 3.0 enables personal computer users to launch Unix applications through Windows icons and create Unix directories from the Windows File Manager. It also enables users to transfer data within a Unix environment by dragging and dropping icons through the Windows File Manager. Directories can be created based on the new multiple-mount-point capability of the Incognito/FS utility, part of the Incognito package. Users can define up to eight of the Unix directories they most frequently use; these will then appear as drives in the Windows File Manager. A new application programming interface, which Opus had been using in-house, gives users a more transparent pipeline for moving data from personal computers to Unix systems for three-dimensional image manipulation. With the package comes: Incognito/Share, which runs as a terminate-and-stay resident program, communicating between the MS-DOS+Windows and the Unix environments so that peripherals can be shared; and Incognito/Launch which eases personal computer access to Sparcstation applications. Incognito runs on iAPX-86 personal computers with a Sparcard add-in board. This version supports Solaris 2.X. Incognito/Share is $245; Incognito/FS, $200; and Incognito/Launch, $100.
