(I asked this question a few weeks ago.  Here is what I found out:)

To use the HP 7475A plotter with the S statistical system, use the
"hpgl" driver.  To do this, you must have the correct hardware
configuration.
				_______________
				| Plotter     |
				|_____________|

				|-------------|
The cable also has another part number, which might be 17455 (?).

The switch settings we use are: S2=0 S1=0 (Parity)   D/Y=1(=Y) US/MET=1(=US)
A3/A4=0 (Paper size A4)  (B4,B3,B2,B1)=1010 (Baud rate=9600(?))

HPGL is the HP graphics language, which works for a number of HP
graphics devices.  The 7475A has some extensions on the language,
which are presumably not supported by S, but we've been quite
satisfied with it.

Thanks to those whose advice contributed to this.
