Wanted: High-res picture of Technos Double Dragon Board IC

Archived from groups: rec.games.video.arcade.collecting (More info?)

Hi.

Myself and my friends are wondering if there's a kind hearted person
out there with a digital camera and five minutes to spare.

As it seems there's no hope of finding a schematic of Double Dragon
anywhere, we're wondering if someone could take a high-res picture of
the PCB top, paying particular detail to the area near the jamma
connector.

If the jamma connector if on the left and the board interconnects on
the right; there are some capacitors in the top left corner of the
board. Just next to these is a chip with 9/10 pins in a row on one
side of the chip, which is also fixed to the board with two screws,
rectangular in shape.

We need either a very good picture of the top of the chip, where the
text is legible, or a return post with the text.

Thanks very much,

Jez (and Dan)

Hey Rob,

We're pretty sure it's the sound amp as well, probably a Mitsubishi IC.
If we can't fix it (which is part of the fun), we may well take you up
on it :-)

It's a Motorola M51516L
