The Acorn Network Computer was a network computer (a type of thin client[https://books.google.com/books?id=HJ-xQWUx1vwC&dq=Acorn+Network+Computer+thin+client&pg=PA31 Technology and the School Library: A Comprehensive Guide for Media Specialists and Other Educators], Odin L. Jurkowski, Lanham, Md. : Scarecrow Press, 2010, p.31) designed and manufactured by Acorn Computers Ltd. It was the implementation of the Network Computer Reference Profile that Oracle Corporation commissioned Acorn to specify for network computers (for more detail on the history, see Acorn's Network Computer). Sophie Wilson of Acorn led the effort. It was launched in August 1996.
The NCOS operating system used in this first implementation was based on RISC OS and ran on ARM hardware.

Hardware models
=Original model=
The NetStation was available in two versions, one with a modem for home use via a television, and a version with an Ethernet card for use in businesses and schools with VGA monitors and an on-site BSD Unix fileserver based on RiscBSD, an early ARM port of NetBSD. Both versions were upgradable, as the modem and Ethernet cards were replaceable "podules" (Acorn-format Eurocards). The home version was trialled in 1997/98 in conjunction with BT.{{cite news | url=http://www.zdnet.co.uk/news/it-strategy/1997/06/11/acorn-and-bt-trial-consumer-nc-2065965/ | title=Acorn and BT trial consumer NC | work=ZDNet | date=June 11, 1997 | accessdate=December 15, 2011 | quote=The trial will combine Acorn's NC technology with BT's communications network and will be centred around BT's laboratories in Martlesham, Suffolk.

The {{nowrap|Home NC}} and {{nowrap|Corporate NC}} both used the {{nowrap|ARM 7500FE}} and supported PAL, NTSC and SVGA displays. They had identical specifications.

Acorn continued to produce ARM-based designs, demonstrating its first StrongARM prototype in May 1996,

=Later versions=
The second generation Network Computer operating system was no longer based on RISC OS. NC Desktop, from Oracle subsidiary Network Computer Inc., instead combined NetBSD and the X Window System, featuring desktop windows whose contents were typically described using HTML, reminiscent of (but not entirely equivalent to) the use of Display PostScript in NeXTStep. The product ran on ARM, StrongARM and x86 architectures and could be run on traditional personal computers.{{ cite magazine | url=https://archive.org/details/eu_BYTE-1997-07_OCR/page/n85/mode/2up | title=Good-Bye, GUI HELLO NUI | magazine=Byte | last1=Halfhill | first1=Tom R. | date=July 1997 | access-date=17 August 2023 | pages=60–64, 66, 68, 70, 72 }} NC Desktop was the recommended software solution for products based on the StrongARM-based Digital Network Appliance Reference Design (DNARD).{{ cite book | url=https://archive.org/details/bitsavers_decsrcDNARsGuide199711_260562/page/1-2/mode/2up | title=DIGITAL Network Appliance Reference Design User's Guide | publisher=Digital Equipment Corporation | date=November 1997 | access-date=18 August 2023 | pages=1-2–1-3 }} Later NCs were produced based on the Intel Pentium architecture such as products from Accton Technology Corporation{{ cite magazine | url=https://archive.org/details/networkworld1439unse/page/22/mode/1up | title=New NCs bolster Java and multimedia apps performance | magazine=Network World | last1=Cox | first1=John | date=29 September 1997 | access-date=18 August 2023 | pages=22 }} and UMAX Data Systems.{{ cite magazine | url=https://archive.org/details/networkworld1439unse/page/22/mode/1up | title=Another NC contender enters the ring | magazine=Network World | last1=Ohlson | first1=Kathleen | date=29 September 1997 | access-date=18 August 2023 | pages=22 }}
