Hewlett-Packard Co is happy enough with the performance of its original HP Windows Client, announced back in July and intended to be an ultra-low-cost route into graphical user interfaces for character-based terminal users, that it has extended the family with a faster Model 433SX, also available as an upgrade for the 425SX. The new model in the diskless line has an expanded high-resolution colour palette, 33MHz Intel 80486SX processor and three times the video performance, by virtue of a hardware graphics accelerator and 1Mb dedicated video memory. It comes bundled with MS-DOS 6.0, Windows 3.1 and Reflection 1 and 2 for Windows terminal emulation and Reflection Network Series networking software from Walker Richer & Quinn Inc, plus 4Mb memory, local bus video, keyboard, mouse and a built-in Ethernet connector. There is a new 17 display option for both models, which puts up 256 high-resolution colours against 16 for the 425SX, and offers screen resolutions up to 1,024 by 768 pixels. It costs $1,245 with base monitor, $2,525 with the new one. Upgrading a 425SX costs $600, and the required Server Kit software, which is $500, is offered free to Windows Client buyers in the US until the end of the year.
