Here's a link to all the blog posts discussing its development:

- unwind 2y agoThanks that was a useful clarification/update. Fun to see that the board did gain more chips compared to the image in the posted article, that it gained the ability for "in the field" firmware updates without JTAG hardware, and (most impressively, in a way) that it made it to market after all!
- retrogeek 2y agoAgreed. Better to link to the current info, as the Yellowstone was commercially released a little more than two years ago. I own a Yellowstone (as well as two BMOW Floppy Emus), and it's a pretty impressive controller. It will operate essentially every type of floppy drive that was available for the Apple II, and even some models of Mac floppy drives including bare drive mechanisms if you connect them up properly. It supports as many as five drive mechanisms at one time, and can control "smart" drives and "dumb" drives at the same time. The only thing it won't do is handle HD 1.44M/1.6M media. It can use an HD drive mechanism, but will operate it as a basic 800K drive.
