> I thought that seller had permission? I don't remember what license, if any, Sergey chose for his work. Perhaps it's in compliance. In any case, it's not a new design -- Sergey's wasn't either, it was an improvement on the N8VEM XT-FDC project.
I intend on redoing Sergey's design, with permission, at some point in the not too distant future. Personally, I want a DC37 and both card edge and pin header internal 34-pin connections, so that I can drop the board in as a replacement for a PC or XT floppy controller without changing cables. As with the XT-IDE, onboard serial doesn't seem like much of a feature to me. I've avoided redoing any of Sergey's designs as he'd contacted me some time ago asking how the kit thing was working out with XT-IDEs. It'd sounded like he intended to maybe run some of his designs and provide kits and/or assembled+tested boards for hobbyists. I probably ought to reach out to him and see if that's still the case or not.
