Editing IBM 5120 (section)

==Description==
It was launched in 1980 as the lowest-priced IBM business computer to date. Depending on the options the overall system prices ranged from $9,340 to $23,990. To emphasize its office image IBM released in that same year 6 new programs: task inventory, billing, payroll, accounts payable, accounts receivable and general ledger accounting.<ref name=archives/> 

Aside from larger screen size and performance benefits over its predecessor, the IBM 5120 design incorporated several [[usability]] advantages:
* Reduced 'footprint' requiring less desktop space
* Reduced glare on monitor, keytop and product surfaces
* Ease of handling/lifting based on bottom form treatment
* Reduced static loading in arms and shoulders due to keyboard palm rest

For its usability features and appearance, the IBM 5120 was recognized with two major industrial design awards and described with terms such as "clean, well thought out"; "subtle detailing shows great care in execution"; and "looks like quality{{pprime}}.<ref>{{pprime}}Annual Design Review".

IBM did not offer a [[local area network|LAN]] or [[hard disk drive]] for these systems. However, in 1981, [[Hal Prewitt]], founder of [[Core International|Core International, Inc]], invented and marketed the world's first and only hard disk subsystems and "CoreNet", a LAN used to share programs and data for the IBM 5110 and 5120 systems.<ref>{{cite web|url=http://www.coreinternational.info/1981_5110_Disk_Brochure.pdf|title=''Save IBM 5110/20 from junk yards of the world''|publisher=Core|accessdate=31 March 2010|archive-url=https://web.archive.org/web/20110721193112/http://www.coreinternational.info/1981_5110_Disk_Brochure.pdf |archive-date=21 July 2011}}</ref><ref>{{cite web|url=http://www.coreinternational.info/1982_Sept_CORE_Newsletter.pdf|title=''1982 CORE Newsletter''|publisher=Core|accessdate=18 Nov 2016 |archive-url=https://web.archive.org/web/20161119062654/http://www.coreinternational.info/1982_Sept_CORE_Newsletter.pdf |archive-date=19 November 2016}}</ref> In 1984, Core introduced PC51, software that allowed 5100 Series computer programs written in BASIC to run unmodified on the [[IBM Personal Computer|IBM PC]] and [[IBM PC compatible|compatibles]] under [[IBM PC DOS|PC DOS]] and share programs and data on CoreNet, the LAN for all these models.
