They tried something like that in the late 1980’s with the PS/2 with a proprietary bus. It was up there with the PC Junior in product blunders.

I've even heard IBM engineers complain about their system. For example, if the computer had a standard TI 7400 logic chip in it, they had to use the IBM chip designation and IBM documentation only for the chips that were actually approved for the design. And woe be upon the engineer who had a TI TTL data book hidden in the back drawer of his desk. One engineer I talked to said he had to talk to the suppliers from his home phone and have the databooks delivered to his house so his dark secret wouldn't be found out... although all of the designers did exactly the same thing.

I think they finally broke that insanity sometime in the 1990s.

My nephew had a PC Jr. He became the tech advisor to the office staff when he was in middle school. None of the adults could figure anything out.
