Anyone make a replacement MVS6 Credit display?
Drnick:
Evening,
I have a project in the works (Although project is happening very slowly) to recreate an MVS-6 Big Red Neo Geo, It will be built with vertical Display and will Run mame from PC.
Part of what I would like to do is have working credit displays, So basically I need a 2 digit 7 segment display that can interact with the credit in and start buttons to count up and down.
I have seen a number of people selling replacement credit boards but I assume they get all their data from the Neo Board itself and I need them to be self contained.
I have found the following from malaysia which I will get a friend to order a couple of as he has family over there, I figure at the cost they are if I can't make it do what I want then I'll find something else to do with them.

The Immediate issues with this device are that it runs from PP9 battery (No great shakes, I can drop 12v down to 9). It's more that it only has count up and reset. Ideally I want it to have increase/decrease and not just reset to 0.
So anyone made anything similar? I'm not brilliant with a soldering iron due to the shakes so Ideally something premade would be nice, or a plan I can send to someone to make up for me.

Interesting. Any details on how you intend to make this work? I am a neo geo mame guy too.

Fairly simple really I want the counter to go up when I put in a token or press a credit button, and then I want it to go down when I press start to start a game :)
Ideally I want to find a counter that uses the same active high or active low as whatever I use for the controls (It will not be a zero delay, I know that much).
The only thing I haven't really got around to is finding out what I need to do to make sure that there is no cross voltage from the counters board to the controller board. I'm fairly sure there is something out there to take care of that though :)
