new HP 9000 options was December 31, 2009, with a last ship date of 1 April 2010. HP intends to support these systems through to 2013, with possible extensions. The end of life for HP 9000 also marks the end of an era, as it essentially marks HP's withdrawal from the Unix workstation market (the HP 9000 workstations are end of life, and there are no HP Integrity workstations, so there is no longer a solution which targets HP/UX at the desktop). When the move from PA-RISC (9000) to Itanium (Integrity) was announced, Integrity workstations running either HP/UX or Windows were initially announced and offered, but were moved to end of sales life relatively quickly, with no replacement (arguably because x86-64 made IA-64 uncompetitive on the desktop, and HP/UX does not support x86-64, with HP offering desktop Linux as an alternative, not fully compatible, solution).

The first model was the HP 9826A, followed by the HP 9836A. Later, a color version of the 9836 (9836C) was introduced. There was also a rack-mount version, the HP 9920A. These were all based on the Motorola 68000 chip. There were 'S' versions of the models that included memory bundled in. When HP-UX was included as an OS, there was a 'U' version of the 9836s and 9920 that used the 68012
