7MB File I may have to split it with WinRAR Can you open it if I post it?

Me either. I looked thru all of the listed logos for hours and still can not find it.

Can't find much http://docs-asia.electrocomponents.com/webdocs/0382/0900766b80382935.pdf

Here is another one that uses a Coil from a car.

Here are some more.

LOL Nice come back.

TTL means Transistor Transistor Logic. This has a Transistor output does it not?

HCPL-7611 Datasheet http://www.avagotech.co.jp/assets/downloadDocument.do?id=1949 http://dspace.dial.pipex.com/isocom/csm170.htm CSM170

I will find the other Datasheet when I have more time. Here is what I have so far. http://www3.telus.net/chemelec/Projects/Alarm/Laser-Alarm.htm [img width=680 height=274] http://www.ee.ryerson.ca/~phiscock/papers/photo-detector.pdf

I looked thru all of these and found nothing! http://www.dialelec.com/semiconductorlogos.html http://freespace.virgin.net/matt.waite/resource/logos/index.htm http://www.elnec.com/iclogos_l.php http://www.rfcafe.com/vendors/logos/logos_f-o.htm http://www.chipdocs.com/logos/logotypes.html http://www.classiccmp.org/rtellason/logos/semiconductorlogos.html http://www.cpushack.net/logos.html http://www.engineering.uiowa.edu/~eshop/mflogo.dir/ic-id.html http://www.eyesurf.co.uk/~nutteing/logotext.htm http://geocities.com/total_project_solutions/icmanufacturerslogo.pdf http://www.embeddedlinks.com/chipdir/c/logo.htm

The only Service Manual I could Find is JD199E I also found the Schematic foe JD199A J199-AMPJ91A.pdf

Type this in Google or Yahoo pnx8316

A websearch results many. Here is one http://digchip.com/distributors/parts/mc/parts_mc-12.php

Double Post or more? Here is your answer http://www.electronics-lab.com/forum/index.php?topic=9060.0

3N80 Datasheet. 3N80.pdf

My educated Guess? An Electromagnet to demonstrate how Magnitisum works.

You should read the notes before attempting to build the circuit Ante Posted. The project is located at http://www3.telus.net/chemelec/Projects/MC1466/MC1466.htm

Here is the Datasheet MC1466L.pdf

I just look online at the same site. http://nte01.nteinc.com/nte/NTExRefSemiProd.nsf/$$Search?OpenForm

Here is the Datasheet. There are many substitutes that will fill the space. 2N5777_MOD.pdf

Sounds like you have a real project on your hands. Here are a couple of Links that you may be interested in. http://www.oldengine.org/members/diesel/Indicator/Indicator1.htm http://www.gutenberg.org/files/10998/10998-h/10998-h.htm

You could use a series of deviders.
