Rossum has a new project out, a little Atari 810 disk drive:
My first computer was an Atari 400. My first disk drive was the magnificent Atari 810. Overwhelmed by a recent wave of nostalgia from playing Zork for the first time in 30 years I have built a working model of an Atari 810 that uses 8Gig microSD cards instead of 5 1/4 inch floppies to emulate up to 8 drives. Maintaining the relative dimensions of drive to media, the model is somewhat smaller than the original.
