Isn’t she just misunderstood? The Casio Loopy!

The Casio Loopy is a 32-bit machine with a SuperH CPU, released in 1995. This family of CPUs is probably more famous for its use by Sega, but the SH7201 used in the Loopy appears to be still in production by Renesas. I'm not sure how much the SH7201 has changed over that time; it seems to be an SH-1 system, as opposed to the SH-2 used in the 32X and Saturn, and the SH-4 used in the Dreamcast.

The Loopy is a treasure. If you've never heard of this thing before - you're in for a treat.
