The wiring diagram for the mini-din connector in v8n128 was incorrect.
The correct wiring diagram for the cable connector is:

	6   7   8

	3   4   5

	  1   2

The pin numbers for the connector on the pizza box would be mirror imaged
from this diagram. We have both microphone input and speaker output with a
cable built according to this diagram and the table in the Sparcstation 1
SunOS 4.0.3 Sun-4c release notes:

Pin 3	Mic. tip
Pin 6	Mic. ring
Pin 7	Speaker ring (sleeve)
Pin 8	Speaker tip (center connections - not stereo)

We bought our microphone and self-amplifying speaker (MPS-5 model
32-2031A) from Radio Shack. The speaker was about $20 and the microphone
(33-992c) was about $28.
