Konami (2000-2001)
A semi-standard stack used to run a multitude of rhythm games from Konami. These are notoriously finicky and most of the time the parts cannot be shared between games due to slightly different board layouts.
Configurations:
No manuals currently added.
Missing lights may be related to the idec NRPS11-6A PCB-mount circuit breaker, located near the I/O harness connector, directly below the RTC. Replacing this with a new circuit breaker allowed the lights to function normally.
There are a pair of batteries powering the RTCRAM on the main board which contains some system settings as well as a license file. If the batteries run out, most Firebeat software will display a license screen and ask you to call Konami. You can use the following keygen to enter a valid password to unlock your device : https://987123879113.github.io/firebeatrtc/
Note that you can replace the batteries as they are wired in parallel. If you replace them carefully one at a time with new batteries you should never encounter that password screen in the first place.
There is a 9 pin connector under the LINE OUT and LINE OUT (AUX) RCA connectors. This 9 pin connector is supposed to be wired to a volume pot which controls the LINE OUT level.
If you don't have a volume pot, you can join pin 2 with pin 4, and join pin 3 with pin 5 (assuming pin 1 on top)
