Reminiscent of the Ampro Littleboard, which was a single-board CP/M computer designed to fit over a floppy drive, and was the direct ancestor of PC-104 and similar single-board computers. I had the pleasure of meeting one of Ampro's retired founders, I don't remember which, at a Vintage Computer Festival (I think) about twenty years ago. It was next over from the Amiga prototype, which was out unattended and I got to touch.
