Hexagram 54: 歸妹
guī mèi — little sister's marriage, marrying maiden
Judgment
The marrying maiden. Undertakings bring misfortune. Nothing that would further. The secondary position must not attempt to supplant the primary. Maintain tactful reserve. Relationships based on inclination depend on careful behavior.
Image
Thunder over the lake: the image of the marrying maiden. Thus the superior man understands the transitory in the light of the eternity of the end. Remain mindful of enduring principles. Don't drift—fix your mind on what lasts.

MS-DOS's Relationship with CP/M
Tim Paterson (QDOS/86-DOS) (1981)
In 1980, Seattle Computer Products needed an OS for 8086 boards. CP/M-86 wasn't ready. Tim Paterson wrote QDOS—Quick and Dirty Operating System—explicitly modeled on CP/M but rewritten for 8086. Not the primary wife; the concubine. QDOS knew its place: provide CP/M-like functionality until real CP/M-86 arrived. Then Microsoft bought it, renamed it MS-DOS, licensed it to IBM. Suddenly the secondary option became standard. Thunder above, Lake below—the eldest son leads, youngest daughter follows. MS-DOS always followed CP/M's footsteps, conventions, command structure. Never innovator, always follower. But the follower won—through tactical reserve, timing, understanding its actual position. The marrying maiden making herself indispensable.
