==Remaining machines==

Despite having been sold or leased in very large numbers for a [[mainframe computer|mainframe]] system of its era, only a few of System/360 Model 20 computers remain. These are primarily the property of museums or collectors. Examples of existing systems include:

* Two Model 20 processors along with numerous peripherals (forming at least one complete system) located in Nürnberg, Germany were purchased on [[eBay]] in April/May 2019 for €3710 by two UK enthusiasts who, over the course of some months, moved the machine to [[Creslow Park]] in [[Buckinghamshire]], United Kingdom. The system was in a small, abandoned building left untouched for decades, and apparently had been used in that building since all peripherals were still fully wired and interconnected.<ref name="ibms360">{{cite web|url=https://ibms360.co.uk/?page_id=22|title=Project History|website=IBM 360 Model 20 Rescue & Restoration|access-date=2019-05-20|year=2019}}</ref> As of September 2024 the systems have been moved on a long-term loan basis to the [[System Source Computer Museum]] in [[Hunt Valley, Maryland]], USA for display and restoration.<ref>{{cite web|title=The 360’s have a new home!|work=IBM 360 Model 20 Rescue & Restoration Blog|date=September 11, 2024|url = https://www.ibm360.co.uk/?p=916}}</ref>
