DOS/360 required a System/360 CPU (model 25 and above) with the standard instruction set (decimal and floating-point instruction sets optional).  The minimum memory requirement was 16&nbsp;KB; storage protection was required only if multiprogramming was used.  A [[IBM 1050|1052 Model 7]]<ref group=NB>DOS/360 on a S/370 used a 3210 or a 3215 rather than a 1052-7</ref> printer-keyboard, either a selector or multiplexor [[IBM System/360#Channels|channel]], and at least one disk drive was required — initially a [[IBM 2311|2311]] holding 7.25&nbsp;MB.  A [[Punched card input/output|card reader]], [[Punched card input/output|card punch]] and [[line printer]] were usually included, but [[Magnetic tape data storage|magnetic tape drives]] could be substituted.<ref name=sysgen/>{{rp|p.10}}

A ''typical'' configuration might consist of a S/360 model 30 with 32KB memory and the decimal instruction set, an [[IBM 2540]] card reader/card punch, an [[IBM 1403]] printer, two or three IBM 2311 disks, two IBM 2415 magnetic tape drives, and the 1052-7 console.
