Wiring up the Sega/CD32 adapter

A few weeks ago I pushed the PSoC Creator project for my Sega-6-button-to-CD32 converter project, but anyone wishing to build a converter would need to know the pin mapping.  This is defined within the Creator project, but figuring out which pins on the DB9s need to be wired to which terminals on the board would be pretty tedious – so here’s a wiring diagram for the benefit of anyone who wants to have a go.

(Please note, the board shown here is the CY8CKIT-049-42XX – the identical-looking 41XX won’t work because the chip lacks the programmable logic the project uses to create the shift register.)
