Neo Geo MVS-ELA (lamp driver) schematic/parts list?
« on: September 14, 2005, 12:49:34 pm »
This is the little board that drives the EL panels which light up from game to game in a Neo Geo cab, does anyone have a schematic, or a parts list for it?  Mine is melted  I'd post this at neo-geo dot com forums, but they won't activate my account for some reason.  They're a wee tad insane, anyways.

Here's a picture - http://hardmvs.com/images/parts/MV-ELAsm.jpg

I'll take some up close shots of the components I cant id myself when I get home, there's a funny catipillar looking thing, looks like a tantalum cap with 12 legs or so, right to the left of the ICs in that pic..  i suspect, though, that replacing the ICs (easy enough, 74LSxx parts) and the melted transformer will do the trick - its marked D3-016, can anyone tell me how I go about finding a suitable replacement?

I can't help you with schematics, but I believe the "funny catipillar looking thing" is a resistor network. It's marked CRE401-93.

Good Luck

I don't have a schematic, but I kinda mapped it out a long time ago.  All the info I have from that project can be found
http://www.personal.triticom.com/~erm/Arcade/NeoGeoUprightPics/LEDInstall/
and


There are a bunch of chip PDF's at the bottom of that first link.

And, I know this is a really old question, but I figure others may search for the same thing at times.  Maybe this will help.
