Hi
This has been discussed on this mailinglist before (back in -95 and
-03). But with very little information came out of that.
I'm curious about the "Q Bus Music Board" that DEC made. What system was
it used in, what software was available that took advantage of it, how
would you program it?
All I know is from the cctalk threads and a few pictures from an ebay
auction, with missleading description, that I missed out on. The number
on the green handle is "93 08036" and on the PCB there is the number
"EY-0105E-MS-0101" and it looks like it has two AY-3-8192 synthesiser
chips.
So, does anyone know anything more?
And if anyone has one they could part with, I'd be interested.
Kind Regards,
Pontus.

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).

Ah, another keyword to look for.

Is both code and hardware burried? Preserving the software for reference
might be valuable should I ever find the hardware.

I see, uhm.. what is/was DECworld?

Ah, that explains the odd format (not an M-number).

It certainly looks like a DEC document numbering scheme. In the ebay
auction it was decsribed a an "A6006 Analog output board". I think that
is something entirely different, or is it related?
Thank you for shedding some light on it.

decworld was decus related? i know my father went to one of these
conferences back in the day and won the rainbow100 door prize that they
shipped to him all the way to the remote bush of northern manitoba.

That A6006 produces a hit in this document
http://bitsavers.trailing-edge.com/pdf/dec/qbus/EB-23144-18_QbusIntrfs_1983…
AAV11-C ANALOG OUTPUT BOARD
Table 1, document page 18, PDF page 28 for the index entry
AAV11-C document page 37 PDF page 47 for the description
Interesting board, 4 DACs, and a DC-DC converter.
Thanks

Definitely something else.
Thank you,
