[edit] Migration to horizontal navbox?
After I created it, I've found Template:FamilyTree CP/CMS which has very interesting layout. Maybe it is also worth to use here?
Pro: smybols show important relations: "influence only", "major reimplementation of", "improvement", "rebranding".
Pro: columns can be named S/360, S/370, ..., z9 neatly visualising OS generations as opposed to HW generations.
Pro: is horizontal -> is less awkward if included in stub articles
Con: not WP:AS-style compatible.
Con: is horizontal -> should be included on bottom of article -> is less visible -> is less useful.
[edit] The layout
| CP/CMS family relationships → derivation >> strong influence > some influence/precedence |
|||
| CTSS | |||
| > IBM M44/44X | |||
| >> CP-40/CMS → CP[-67]/CMS | → VM/370 → VM/XA versions → VM/ESA → z/VM | ||
| → VP/CSS | |||
| > TSS/360 | |||
| > TSO for OS/MVT → for OS/VS2 → for MVS → ... → for z/OS | |||
| >> MULTICS and most other time-sharing platforms | |||
This simplified framework provides links to major time-sharing systems that influenced or were influenced by CP/CMS. Many other important systems emerged during this period; cf. Manchester/Ferranti Atlas, Burroughs, Control Data Corporation, DEC, and Honeywell for examples. Also see time-sharing system evolution.
