Jamma to lcd vga monitor

[Pharo]

Hi all picked up a cab last night,it has one of those Chinese jamma looms in it playing a 19-1 board and an LCD monitor in it which isn't great news so the question is what can I do to get to play my jamma boards in it as obviously no VGA connection on the boards,ive have another cab with a crt in it to play these boards but would like to have two running together.
Apart from the LCD screen it's a cracking wee cab.
Cheers Brian

Just don't plug your boards into that crappy loom. 😉

Second what big10p says.

You can wire jamma to vga i think , if i remember i will have a look tomoz.

Edit : its scart you can wire , for vga its the rgb to vga converter , gnobes i think.

Cheers for the replies I think I might just leave it how it is as big 10p says I wouldn't trust plugging my boards into one of these jamma looms,I've got a spare 60-1 board so might put that in instead or might just keep it playing super mario.

I'd just whack a little SFF in it with a J-pac, I'm quite pleased with my set up. Yes it needs an little sound amp and time to set up.

I might do that Darren but the thing is the control panel only has 2 buttons per player it did only have 1 button originally and another has been added at a later date not very well I may add and I don't think it would look right with more buttons as it would waste the Mario control panel overlay.

Is this one of that cabs from Hungary? There is one guy there selling these. Looks good. Dose it have space to put an crt inside?

you can run jamma boards on VGA with a £20-30 GBS8220 from Sintech and a resister divider on the sync line.
make sure you put the resistors or the jamma sync voltages can slowly damage the adapter.
the jamma sync is upto 5v and the GBS8220 has a max input of 3.3v

Don't know if it came from Hungary but it is a full size cab plenty of room for a crt, have you got a link to the one in Hungary and I will compare it.

Thanks for the info but that might be out with my capabilities as I'm guaranteed to do something wrong 😄,as big 10p says it might be a risk plugging a board into one of those crappy Chinese jamma looms.

He has more, all look brand new. Never bought from him.

a voltage divider is the simplets electronic circuit - everybody should learn about then.
just 2 resistors can divide a signal to anything you want.

save you some time, if R1 is 1k and R2 is 2k you get 3.2v out for 5v in

To me that looks exactly the same different coin door but the rest look the same even to the screws and channel that hold the marquee and printed glass,if you want pics of the inside of the cab can do that tonight.
I paid no where near that price and it was only 30 mins from me.

If i was closer I would come and do wiring and sort it for you. Not that hard to do if you dont mind getting your hands dirty, Not much you can get wrong to be fair. As you said though using a multi in there would be fine. Issue with cheap cables are the power consumption , they are not thick enough to take the ' Umph '.

Nice looking cab though,

Dave.

Ha ha you could have and we could have had a 2 player game of wonderboy and you might have got some tips off me 🤣

GRRRRRR , lol !!



I will catch you , And overtake you, Mark my words ! lol.

Need to get a proper cab sorted asap.

Dave.

 

[Pharo]

🤣my mate with the printing business is still on the case he's not sure what to do with the control panel yet and as my cab is a midi leisure 2000 there is no marquee and also the print on the glass so he wants time to think about it.

Yeh will need shrinking and re positioning ?? I assume anyways.

You got pics of it ??

Here's some pics of the cab I'm going to use for it.
