Description
Allows you to use your Nintendo classic pre-JAMMA Donkey Kong TKG3 or Radar Scope PCBs, in a JAMMA cabinet or a super gun device.
While most of Nintendo games produced between 1980 and 1984 used the same pinout, the early games did not. During the very early 80s, Nintendo used hardware that consisted of multiple smaller boards (3 or 4) that could be used in cocktail cabinets. Instead of an edge connector, a series of headers were used for cabinet connectivity. This type of connector was used on games like Space Firebird and others, but only the TKG3 Donkey Kong and Radar Scope boardsets have these connectors in the same location that serve the exact same function.
There are different versions of the TKG3 sound boards. Some have a built-in audio amp, some do not. This adapter supports both. The adapter also has a built-in audio amp that can be bypassed with a single jumper, and a low cost, high speed video inverter that converts the inverted video to a signal that is compatible with the JAMMA standard. The signal DC offset for each color (Red, Green and Blue) can be adjusted to display properly on a standard arcade monitor.
The cables required to connect the PCB to the adapter are included, however the rainbow interconnect cables for the PCB layers are not. Please ensure your PCB still has those.

Important: Female connector headers on this adapter are tight fitting and not the exact type as the ones inside original the cabinet (original ones are unobtainum). Care must be used when inserting and removing this adapter from the PCB or the connectors may be damaged. Carefully pry the right side of the adapter off first then move towards the left side.
Compatible Games
This is the list of compatible games that can be used with this adapter:
- Donkey Kong (TKG3 boardsets)
- Radar Scope
Important: Radar Scope requires at least 5 Amps of current on the -5V rail. Typical arcade power supplies produce only about 1A of current on the -5V. You will need to find a suitable power supply, or add a second PSU and use its 5V rail (tie +5V to GND and use GND as -5V) to generate the required -5V. The game will not boot otherwise.
The adapter has been tested with genuine Nintendo Donkey Kong and Radar Scope boards for compatibility.
