How's the DK sounds on that 60-in-1?  If I remember correctly, those boards have some crummy sound emulation for certain games, I think due to some older version of mame they hacked together for these.
I've only messed around with a 60-in-1 once before, but I vaguely remember DK, DK jr. and 1942 having some really scratchy audio.

You are right. The sound is crap!

Well, It might not stay in there for long.

What I received was this. 100 of them! 

Why can't this happen to me when I order something like a PS4?

[opt2not]

What are you going to do with 100 PS4's??   (aside the obvious selling of them)

That's what's cool about you wiring it for Jamma. You can easily swap it out later. The ArcadeSD is pricey but it is a much better option.

2 dumb Questions about the Arcade SD:

1. I assume you need a scan line generator for the authentic look if you are using an LCD?

2. I'm confused how you play horizontal games on a vertical monitor and vise versa? Is the menu system rotated 90 degrees all the time if you catch my drift?

3rd dumd question about the ArcadeSD: does it come in blue? No, can you connect it directly to a jamma cab without doing anything video-wise?

So today I made the SCART-RGB cable. I'm very satisfied with this one. It looks like it's just came out of the SCART-RGB factory.




And it works!


So now I have to figure out how the hell I'm gonna mount that TV.

Decase it

Of course. And then what?

Couple globs of hot glue should hold her down.



...just kidding, I have no idea how your mounting that thing.

I have a method. Once I get to a computer I will search the topics where I posted it.

[DeLuSioNal29]

I think I mentioned it earlier in this thread but here it is again (this time with link and pics):
I mounted a 19" de-cased PC CRT monitor in one of my cabs and it was easy using the method below.  I didn't bother with a frame although I did use the existing brackets in the machine (mine were made of wood but you could also use metal ones that are in the machine already).

I simply de-cased the monitor and attached this electrical gang box cover (90 cents at Lowes or Home Depot) to the monitor bolts on all 4 corners.


Then you simply rotate the covers to line up with the existing holes on the brackets and drill a hole for each.  Solid fit without the fuss and cheap as all heck.






You can do the same with a TV which should have the same 4 bolts.

Thanks! So what about the chassis? How did you mount that? Just screwed it to a shelf or the side of the cab?

[DeLuSioNal29]

When you decase it, just the front and back come off. The chassis should remain intact to some sort of frame.

I need some measurements, please. Can somebody measure the red, blue and green lines on this pic: Please??? 


I know they wont be exact, but it would help nevertheless.

[ChanceKJ]

[johnrt]

These measurements are taken from the centre of the monitor, not the corners of the tube. They are approximate.

Green: 9 inches
Red: 20.25 inches

Thanks! What about the blue one?

Ohh... never mind! :-P

[yamatetsu]

I took the pic into a graphics program, enlarged it proportionally and drew the three lines. According to the program,



green is about 210 mm, red is about 518 mm and blue is about 62 mm.

This is such a nice build.

I'm Jealous you get to use a SCART TV. I had an opportunity to pick one up when I was living in Tanzania. Even ordered a SCART to VGA cable off eBay. Had a bit of a time crunch, was moving to Nepal, and I did not get it before the movers came. 

My understanding is if that a SCART tv is functionally identical to a real arcade monitor. You may want to try trading out the 60-1 for Groovy Mame on an old PC. You would need to get an ATI graphics card but a cheep old one should do fine, if all the research I did is correct.

Nope! This will be JAMMA only. Eventually I'll get hold of an ArcadeSD, but for now it's a 60-in-1 with ONE game enabled.

PacMan?

Yeah, right! I find the 60-in-1 so crappy. I'm so glad I ordered it during chinese black friday. I paid next to nothing for the damn ---steaming pile of meadow muffin---.

You might be able to use a J-pac ($59 US) with an old PC (often free) running Groovy MAME (Free)... I think? I don't have a J-pac and Like I said, my plans to use SCART fell apart. It may be worth looking into and would probably be cheeper then an arcade SD ($325 US). 

I ordered a Pandras box 3 kit on 11.11 (Chines black Friday). It has not arrived yet, but am hoping it doesn't suck to much. It was cheep and I wanted to give a xxx-1 a try.

Many TVs and PC monitors don't have the same frame as an arcade monitor because they weren't intended to be decased. Just FYI.

And this is the case for most "modern" CRT TV's. Also for mine. There isn't any frame. I'll figure out something.

I fashioned one out of metal. And another from wood.

Also, if you wanted to go Pi/JAMMA there's now this little beauty on KLOV...

That one I did like!!! And the games loads fast!

You know, I just placed a random monitor picture into the plans in photoshop. I think I'll trust Chance's measurements. But I obviously didn't miss completely.

[johnrt]

So it's time to restore progress on this build also. And now I need these measurements for the service button bracket(A, B, C, D): Chance? Anyone?

Thanks Chance!
