Monitor for Ikari Warriors?

[MaximRecoil]

I was thinking about getting a new monitor for my Ikari Warriors machine (original Dynamo HS-1 "cut-corner" cabinet). Currently it has a WG K4900 monitor with a frame that looks like this:



I'd like to get a Happ Vision Pro. Does anyone know if the shelf-mount version will fit (mounted vertically) in the cabinet without sticking too far out the back preventing the back door from closing?

When I first got that machine it had the 4900 in a triangular shaped frame like this:



And that frame stuck out the back too far for the door to close. The seller transferred the chassis and tube to a compact frame from another 4900, like the frame in the first picture. It looks like the shelf-mount Vision Pro has a similarly shaped triangular frame:



So I'm worried about the Vision Pro not fitting.

Also, where is the best place to buy a new Vision Pro? I'm guessing that getting it directly from Happ's site would have high shipping costs, but would you still get a warranty and/or support from Happ if you bought it elsewhere?

Shelf mount won't work in that  cab.  The mounting holes are in the wrong place.

According to this:



The "aux mounting brackets" can go on the sides or the top and bottom of the monitor. They would need to go on the top and bottom of the monitor for a Dynamo install.

In that case...

In that case...

"In that case" what?

[SirPeale]

In that case it should be fine mounting.  Can't comment on how it sticks out the back, but it's only 17" from front of tube to back of neck.  Measure your existing monitor.

I don't think the neck will be a problem, but rather, the longest part of the triangular frame when mounted vertically. It looks like this distance on the Vision Pro is 12.69" from the mounting brackets. Without taking my monitor out of my cabinet to measure, the best I can come up with for a measurement for this area is 11.5" + 3/4" when you take the board it is mounted to into account, so about 12 1/4". There is about 1/4" of room to spare between the frame and a straight edge across the back door area to simulate the back door. That brings it to 12 1/2". However, there is a little slop in how the back door closes, depending on how the cam on the lock is bent...

So it might be a tight squeeze or it might not fit at all. I don't really trust that added-up compilation of rough measurements I did to the extent that I'd risk the hassle of having a new monitor here that doesn't fit; so I was hoping someone knows for sure; or if they know of a new monitor that will fit for sure. With all the Dynamo cabinets out there, surely someone has installed a new monitor in one.

The monitor shown in your color picture is NOT a 4900. Yours shows a k7600 ("cut in" frame of a k7000).

Dynamo cabinets use "universal" mount frame monitors not shelf mount.

I know. That is not my monitor. It is a picture of a Dynamo cabinet on eBay. It has the same mounting frame as my K4900 though, so I used the picture to illustrate the mounting frame type I have. I have another Dynamo with a K7000 that has the same mounting frame.

Dynamo cabinets use "universal" mount frame monitors not shelf mount.

Well that's good to know. So a Vision Pro in a universal mounting frame like this one will drop right in vertically with no issues?

These new monitors don't need isolation transformers, right? Does it hurt anything to use an isolation transformer with them or is it best to not use the isolation transformer? Also, do you have any suggestions for where I should buy a new Vision Pro?

[Ken Layton]

Yes that Vision pro universal will fit. It doesn't need isolation but it won't hurt it to use one.

Vision Pro is a Happ Controls trademark for their monitors. You buy Vision Pro direct from Happ or one of their dealers.

Happ Controls Vision Pro monitors are actually Tovis brand monitors that Happ rebrands as their own.

Unfortunately the "universal" frame does not fit a Dynamo cabinet. For one thing, some bolt heads on the frame get in the way of it sliding all the way into the mounting board. That's not a big deal, because you could just make some small relief cuts in the mounting board. The real problem is that the frame is too long and the back door will not close. So I transferred it to the K7000 frame.

I installed it in my Street Fighter II: The World Warrior machine rather than in the Ikari Warriors machine (same Dynamo HS-1 cabinet). The K7000 was hooked up with a single sync wire going to the negative horizontal sync pin. So there were 5 wires total: red, green, blue, ground (black) and sync (white). This worked fine with the SFII board and the K7000 monitor, but doesn't seem to work with the same SFII board and the Happ Vision Pro. I get a black screen with a static-type line through the middle horizontally.

How should I hook this up? Do I need to jump a wire over from the negative H-sync to the negative V-sync?

Edit: It's working now. It wasn't a sync issue at all. I'd removed the remote adjustment board while swapping everything over to the K7000 frame to keep it out of my way, and I hadn't hooked it back up yet when I first tested the monitor. I figured it was optional to have it hooked up, but I guess not.
