The board was called Gigilo.

I have one and last I tried it it was operational I also have a minor 
chunk of code to do
some music under RT11.   Currently deeply buried and not in my easy 
search path.

It was as believed at the time I worked for DEC that it was developed 
internally for
things like DECworld.   Its never been clear if it was for QBUS PDP-11 
use or MicroVAX.
I don't think it was ever made in quantity and mine is a unit that was 
floating around
terminal and printers engineering in a random 11/23 that I still have.

The number on the handle was the handle part number and not relevant to 
any product.
The AY-3 are the sound generator chips as it does two channels of sound.
The EY-0105e may be a document (spec or drawing).
