Editing RISC iX (section)

== Distribution ==
RISC iX was either supplied preinstalled on new computer hardware or was installed onsite from a portable [[tape drive]] by Granada Microcare, who would take the installation tape away with them. Upgrades to RISC iX 1.2 from earlier versions started at £349 for R140 machines, and new installations for A400-series machines started at £999.<ref name="acornuser199108" /> Installations required 100&nbsp;MB of space on suitable hard drive or network storage, with hard drive and SCSI card bundles being offered from £1699 for R140 machines and from £2326 for A400-series machines.<ref name="acorn_a252unix" />

Once installed a backup of the core operating system to three [[floppy disk]]s was possible, allowing future reinstallation through the use of remote filesystems or backup media to transfer files to a machine.<ref name="granada_readme">{{cite tech report |url=http://chrisacorns.computinghistory.org.uk/docs/Acorn/Misc/GrenadaReadMe.txt |title=This document gives details of the modus operandi used by the mkfloppies shell script and the three other scripts ( mkkernel, mksystem and mkarchive ) that it invokes. |publisher=Microcare Software Helpdesk |date=1 August 1990 |access-date=13 February 2021}}</ref>
