Midway Multi-Williams Omega MAME

[RetroJames]

I figured it out:

The "+= 2V MAX" refers to the LED - maxvoltage = 2v.  From another switch (same kind, diff mfg) I found they are rated at 10 mA.  They are essentially red leds and the range is around 10 - 20 mA.

The "5A 125/250 VAC" refers to the switch portion, and is the max voltage/amps that should pass through the switch when activated.

On the LEDs, I wired them in series and using this calculator with the following settings;

http://ourworld.compuserve.com/homepages/Bill_Bowden/led.htm

Total LEDs = 4
LED Voltage = 2V
LED Current (mA) = 10
Total Voltage (supply) = 9V
---------------------------------------
Series Resistor = 100 Ohms

So I put in the 100 Ohm resistor on the 9V supply leading to the LED series.

I am going to post a schematic of the CP wiring in a bit.

Holy Crap I never thought I would see the day. I have no pics right now and I have a good sized punch list left before I can call this project done but holy smokes I'm playin' Defender and Robotron and many more.  Playing Defender was the real motivator on this cabinet and I am in seventh heaven.  The CP is fantastic, I was woriied about the 8way joy being used for the up/down but neither the fact that it is eight way nor a bit taller than a stock defender stick is putting any kind of damper on the fun. 

The raster monitor reflected against the mirror/glass in the Omega cabinet looks just awesome, wayyyyy better than I expected.  You cannot tell it is a reflection save for the fact that you can see the actual monitor below.

Sound is good, controls are real tight, and the video modes in advamame are working out pretty well.

I set out to get this thing operational by the end of this week and just finished today.  I have much to do but I can honestly say this entire project was and is waaaaaayyyyyy worth it.  If you are having any doubts, forget 'em and FINISH THAT CABINET!

Awsome.  I'm glad you're playing it finally, just remember not to get caught up and not finish it.  Thanks for the tip on fastvid.  Maybe it will help out my little PII 233 laptop I'm using in one of my projects.

I update the fastvid download link - the first was not working - here it is again -

OMG!!! Thats my vert. cab. I never knew. saw your plastick under your cp.
mine, has that.  I just ran into my arcade room and I see the same shape.
Mine was converted into a Kung fu master thanks .

The thing I think is most intersting about these Omega Race cabs is they are that pressboard stuff.  It's not really wood, but like a dense cardboard.  I don't even know if they make the stuff anymore.

I'm not sure what the best method would be on this type of material.  Sanding may just make it fuzzy or something.  What ever you do, just be sure to wear a mask with this stuff.  If you do make changes/repairs to the cab, post your results.  Mine is mushroomed in the back on top of the cabinet.  I was just going to leave it as is, but if there's a way to fix it, I might try.

I won't be going into that on the Omega Mame in the forseeable future.  My cab is in great shape, just a few rough edges and some small scratches.  The sanding would leave it fuzzy, but you could do that just to get the cancer out.  Once you seal it with epoxy (some products are sandable) then bodo to get it back to the level you want it I think you would be fine.  There is a product that you can use on partially rotted wood, commmonly used on window sills. You glop it on the affected area and it soaks into all the gaps as well as seals the exterior of the wood.  Then you can sand it like it was wood.  I wish i could remember the name of it, it is pretty cool stuff and is often stronger than the rest of the wood you are treating.
