As a fan of antique electronics I just could not resist. I got this through the post today. Been looking for one for a long time.
Not much to look at, but this is the pinnacle (ish) of Nissan electronics from the early Eighties. Its the audible warning unit from a 82/83 280ZX, more colourfully known as 'Bitchin Betty' in the States. I believe they were only available on US cars. The unit lets you know when the doors are open and fuel low amongst other things.
As you can see no chips in here, there is one op amp but thats it. All analogue stuff, lovely.
Now if you look real close at this picture you will see where the lovely voice of Betty is generated. Right in the middle there is a little bitty plastic record disc, just like an LP (for those of us that still remember and use them). For each phrase required a different track on the record is played. The output I believe was via the car stereo. How quaint!
I hope to get a circuit diagram, or failing that map out the inputs and output needed to see if I can get it working.
