• Re: Microchannel Adapter Never Released Commercially?

    From IBMMuseum@21:1/5 to All on Tue Jul 11 22:36:29 2023
    Texas Instrument documentation on an "AN-770" microchannel adapter that had a 16552
    UART chip able to do DMA transfers: https://www.ti.com/lit/an/snla024/snla024.pdf

    The Description File would have been @6E6D.ADF - and is listed within the document.
    It is not in the repository for anything released commercially. Of interest, it is a good
    primer on the 82C611 chip interface.

    I'm bumping this again - the link is still active, but the PDF should be cached and analyzed.

    AN - Application Note. A description on how to use a TI product to do something. I'd be surprised if there is an "AN-770" adapter. Might be,
    but if done, it was/is a prototype...
