I am sorry, but there is no significant historical record of a computing hardware, software, or electronics brand named 'Sovrin' in the context of retro computing or mainstream technology history. The term 'Sovrin' is most commonly associated with modern blockchain-based identity protocols and decentralized identity frameworks, which are contemporary technologies rather than historical computing entities. If you are referring to a specific niche manufacturer or a typo of a different brand name, please provide additional context so I can assist you further.
