Editing Apollo/Domain (section)

==Acquisition==
In 1989, [[Hewlett-Packard]] acquired Apollo. They later released the DN2500 series workstation, a cheap alternative to the DN3x00/4x00 series,<ref name="hpprofessional19891010_lowcost">{{ cite magazine | url=https://archive.org/details/HP-Professional_Vol._03_No._10_Oct_1989/page/42/mode/1up | title=Low-End Workstation Market | magazine=HP Professional | last1=Sharp | first1=Bill | date=October 10, 1989 | access-date=March 5, 2024 | pages=42–44,46 }}</ref> and then the [[HP 9000]] Series 400 line, which can run either HP's own version of [[Unix]], [[HP-UX]], or [[Domain/OS]]. In this case, the choice had to be made at time of purchase, partly because HP-UX and Domain/OS functionality required different keyboards and mice. The Domain/OS variants also include a Token Ring card not provided for the HP-UX variants.<ref name="unixreview199105_testedmettle">{{ cite magazine | url=https://archive.org/details/sim_unix-review_1991-05_9_5/page/63/mode/1up | title=Tested Mettle: Hewlett-Packard 9000/425t | magazine=UNIX Review | last1=Wilson | first1=David | date=May 1991 | access-date=April 26, 2024 | pages=63–67 }}</ref>
