Sharp X68000 Floppy Connector

While this system might be fairly rare outside of Japan, it's currently enjoying a bit of a revival inside Japan. Many popular MegaDrive and SNES games were released for it, and almost always had the better version. Featuring a Motorola 68000 processor (same as the Atari ST, Amiga and Macintosh) with dedicated sound and video processors, the games available for it were pretty phenomenal. Here's the floppy connector pinout, see here for the keyboard port, here for the mouse port, here for the 3D port, and here for the RGB port.
