    The first progress report on the is taking much longer then expected.

    Its turned out quite time consuming to produce more modern representations of the data format.

    Here is a preview of the blogpost in the first image compared to the original programming manual in the second.

    I will probably split the posts in two and only start focusing on the actual Python decoder in a subsequent post.

    No promises yet but I might be able to publish a data decoder for the logic analyzer somewhere tonight together with a (incoherent) blog post.

    This decoder is written in Python as opposed to the eventual driver.

    The analyzers and the Gotek need some small modifications which I hope to do on a ribbon cable or terminal block.

    Among some discrepancies is that HP has 12 volts on pin 33 which is ground on the Gotek.

    There is already a variety of interesting ways many others have solved this over the years.

    These are some examples, 1; by Eduard Cheng, 2; rudiswiki.de, 3; phvidston on Github

    I am currently thinking, we write either a sigrok driver.

    Or we even cut that short and write minimal python just create a dump that Pulseview can import.

    Also depends on my friend who joins in, they might want to go hardmode and do everything from scratch.

    The sigrok driver be interesting because it could be upstreamed lol.
