Hewlett-Packard Co has now introduced the SoftPC Synthetic Hardware that enables HP9000 computer users to run MS-DOS software under the HP-UX implementation of Unix. Insignia Solutions Inc, developer of SoftPC, already has an agreement with Hewlett, which is to license, label, sell and support SoftPC as a Hewlett brand product. SoftPC, which requires no additional hardware, allows the HP 9000 Series 300 workstations and 800 minicomputers to emulate an IBM XT and use standard MS-DOS software, including PC-CAD applications, and is now available for a range of systems from the 68020-based Model 318M through to the RISC-based HP9000 Model 855. The Series 300 version of SoftPC costs $850 with a delivery time of around eight weeks, with the Series 800 versions coming in between $1,275 and $2,750 with an estimated delivery time of 12 weeks. In addition Hewlett has improved the IBM AT-compatible HP 9000/300 MS-DOS co-processor which now supports EGA display emulation, X Window System Version 11, MS-DOS 3.3, and has a larger available address space. The co-processor system, including hardware and software, costs $1,335 and has a delivery time of four weeks. Each product has an expert system-based on-line help facility and hypertext feature for multi-level access to help menus.
