The only difference between the mini-DIN-8 and a DB-9 is the
form-factor (i.e. the mini-din-8 is quite a bit smaller).

You can purchase the DB-9 to mini-din-8 cables from gumstix in either
null-modem (what you use to connect to a PC) or straight thru
varieties.

The Mac used an entirely different pinout on the mini-din-8. I believe
that the one on the gumstix is the same as what's on the Sun
workstations.

That's what you want, although you may need a gender bender. The null
modem cables have a female DB-9 connector on them. I'm not sure what
the straight tru ones use.
