female DIN to dual female RCA

I’m trying to do the same with a XLR/DIN microphone jack. Looking at the
vandenhul.com link that loedown provided, it has wiring for XLR to a
single RCA jack. For the dual RCA cable I have, would I connect both
(left and right) RCA core cables to pin 2 of the XLR or utilize pin 3 of
the XLR for one of the RCA cables?

Thanks.

Baffled by Honeywell proximity sensor

I’ve been given a sample Honeywell capacitative proximity sensor by a
client. He wants me to build a small micro-based project to interface
with it. The sensor is shipped in a bag labeled "992AA12AN-A2", and the
documentation for "992 series" sensors consists of four letter-sized
sides, most of which are multilingual translations of warnings and
mechanical specs. The electrical documentation supplied with this
sensor is a quarter-page and not very meaningful to me. I’ve
photographed it at http://www.larwe.com/honey.jpg – sorry for the nasty
photo, my scanner is being recalcitrant.

The device has a blue wire, a brown wire and a black wire. Looking at
those diagrams – I presume they relate to different versions of the
sensor – I assume that the blue wire is supposed to be +ve, the brown
is -ve, and the black is output. But when I connect a 10VDC supply and
a scope, all I see on the output is 60Hz hum. I added a 500 ohm
resistor between the "output" line and ground, and still all I get is
hum. The device also doesn’t seem to be drawing any appreciable
current.

The only info I can find on the web is a bunch of people offering to
sell me the datasheet, and one company saying that they have stopped
selling it and now sell someone else’s sensor.
Does anyone know how these devices are supposed to work?

RISC Microprocessor…

Hello all,

One of my friends has an arcade jamma board which he dropped and damaged the
microprocessor. The part is labeled ORION IDT 79R4600-100MS. Is it possible if
I purchase a new one it will work? I am unsure how they work, do they get
programmed with sets of instructions or are they like PC processors where you
can swap a dead one with a new one? I am experienced in soldering these type of
SMT components so soldering will be no problem.

My search for this part has not been an easy one either. Any reccomendations of
sites to try? Here is a list of what i’ve tried searching.

www.arrow.com
www.avnet.com
www.mouser.com
www.digikey.com
www.future-active.com
www.alliedelec.com

Any help is greatly appreciated!!! TIA!!!!

RAM chip specs: HY51C4256S-10

Looking for specs. on HY51C4256S-10   This is an old DIP RAM chip.
I tried the usual suspects including DataSheetArchive.com  but no joy.

If I can’t find this particular chip, is there a newer, compatible
chip?  I have an old printer that would benefit from a few more megs of
RAM.

Tnx,
Michael

Digikey calls the things you want "pin receptacles", and has some made
by Mil-Max.  For .040" diameter pins, you want DigiKey ED5024-ND or
ED5023-ND.
