Never used (old stock) cable for connecting the Commodore 64 or Commodore 128 to a composite monitor or newer style televisions having a video and audio RCA type input jack. Not for split chroma/luma inputs. The main distinguishing features of this odd-looking cable is that the 9-pin RGB output of the Commodore 128 goes to an RGB type EIAJ input connector found on certain Sears, Amdek and Panasonic monitors manufactured primarily during the 1980's. However, the 5-pin DIN connector will connect the video DIN output of a Commodore 64 or 128 to a standard color composite monitor or television having RCA-type video and audio inputs. The white RCA connector is for the audio input and the red RCA connector is for the video input of the TV or composite color monitor. Due to the unique design of this cable the DIN to RCA length of the cable is 4 ft. approximately. However, the distance between the RGB connectors for those using this cable on the Sears, Amdek and/or Panasonic monitors (from the 1980's) is only 3 ft. According to Gemini (artificial intelligence) the Panasonic DT-D1300D monitor had these type of inputs for use with the Commodore 128. However the sister model of this Panasonic DT-D1300D which was the Panasonic CT-D1300D (which looked identical on the outside) apparently had an analog RGB input which would not work with the Commodore 128.Also, according to Gemini (artificial intelligence) the Sears LXI Series 13" Color TV/Monitor (e.g. Model 564.40843652) & SR-2000 had excellent compatibility with the Commodore 128 and needed this style of EIAJ (E8M) connector.Likewise, according to Gemini (artificial intelligence) the Amdek Color II (also known as the Amdek Color 2) monitor used this same 8-pin "Type-I" EIAJ-8 cable for it's RGB capability but the Amdek Color II lacked a composite video input and could not display the 40-column capability of the Commodore 64 or 128.So, here is your chance to own a piece of history. Especially if you have one of the aforementioned Panasonic, Sears and/or Amdek monitors. If you only have a regular composite color monitor or television you should still be able to use this cable but only for standard 40-column color. Tip: If you plan to use this cable without using the RGB connectors you may want to put a piece of scotch tape over the RGB connectors to keep the dust out of them.
