The connectors on my radio
I have an IC-7606MkIIG radio. It has ports on the back. The "data socket" is a 6-pin mini-DIN connector. The "Accessory" connection is a 13-pin DIN connector. The RTTY connector is a 1/8-inch stereo jack, and the CI-V plug is also a 1/8-inch stereo jack. The key is a quarter-inch stereo jack and the microphone connector is an RJ-45. The external speaker is a 1/8-inch mono jack.
The hard connector to get is the 13-pin DIN accessory connector. However, a number of places including BUXCOMM has the connector, either loose or attached to a pigtail. Getting the one with the pigtail is preferred, to avoid all the hassle of soldering the connector. You can also search for "13 pin DIN connector" on your favorite search engine to find similar things.
