Hello! I know very little about arcades! I am learning a TON from my Asteroids project, but still not nearly qualified to even begin on many projects! With that said - I bought another project..... a Donkey Kong Junior.
This machine is essentially working. The image on the monitor has a lot of lines through it, but I can see it showing the gameplay. I can see the text that says insert coin, and it shows through the demo to entice players.
However, there are a few issues and with me being so new to this, I thought I would turn here for some help.
For starters, there is no sound. After some reading, I think there is a sound board/amp/something-rather. I haven't checked the caps on it, but if I recall, I believe there is some sort of an LED on there, and I don't recall seeing mine have an LED light up - if there was even one there.
The monitor - as I said - produces an image that is very hard to see. I am probably going to start with a cap kit on this and see what it produces. Who sells cap kits for DKJR? If this doesn't clean up the monitor (I'll post pics when I get home of what it does), any recommendations?
Lastly - it doesn't appear that the coin door is working properly. It doesn't register that a coin has been inserted. I checked the coin pin-outs on the board, and they're getting 5v, but I can put a coin in both slots, and the text still says "insert coin" - any ideas as to what to do here?
I'll attach a few pics! I paid $200 for the machine and am very very happy with it!
