:-? I remember seeing something like that, though I don't remember what it was called. It was a while back, a year or more, so the details may be fuzzy. The unit that I remember fit inside a PC's 5¼" drive bay, and included its own 3½" floppy DF0:, and 2½" hard drive. Connections to the PC's motherboard allowed for sharing of the monitor, keyboard, and mouse. I recall thinking that it appeared to be a solution in search of a problem; I couldn't think of anything that someone could need it for.
As I recall, only a few made, and Olegil had ordered one, though I don't remember hearing more after that.
