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.
https://www.mybotic.com.my/products/MB-09-2-Digits-Counter-Up-Hobby-Kit/2081The 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.
