world has used mini-din connectors for most everything (including
RS-232
level signals) for a long time.
The original Macintosh used DB-9 connectors for the serial ports,
although the pin-outs were very different from the PC-style DB-9
connections of today.
With the Macintosh Plus, the DB-9 gave way to the mini DIN-8
connector, in part to save space to make room for the DB-25 which
connects the SCSI port.
Apple kept with the mini DIN-8 serial connectors until 1998, with the
iMac, and 1999, with the rest of the product line, where serial ports
were phased out entirely.
Although USB serial adapters are available with mini DIN-8 connectors
from a variety of vendors, I prefer those with the DB-9 connection,
since cables are a little easier to find, and certainly much easier
to build. (mini DIN-8 connectors are terribly difficult to solder)
