Hewlett-Packard Co has again fleshed out its HP9000 RISC-based Unix family at the lower end with the launch of the Model 822S, aimed at distributed client-server office and lab environments. US list price is $27,900, and it is to ship in June. It comes with up to four disk drives and a digital-audio-tape cassette drive storing up to 1.3Gb, in a deskside unit. The 13th Hewlett RISC machine to run HP-UX Unix, the processor board can be swapped on-site to upgrade the thing to a Model 832S, doubling the performance. The company also said it cut the entry HP9000 Model 808S by 19% to $18,000 and of the Model 815S 34% to $19,500.
