This processor architecture is the first 32-bit successor of a series
of extremely bizarre 8 and 16 bit processors by Hitachi. It has a
very strange instruction set and MMU, and developers find it quite a
challenge to map their knowledge of Unix low-level ideas to the
processor architecture.

All the board models have a 5-pin connector (called CN7) which the cable

A USL-5P is shown with a modified IO-DATA cable. In this case the cable
has been shortened significantly and the DB9 connector is glued into a slot
carefully cut into the plastic between the ethernet and a USB port.
