Teac 80-8 VS-88 vari-speed box

Very rare unit, I have  only ever seen this one.

Its the standalone unit with a UK power plug, it needs to connect with the unit via a 6 pin WAKA plug same as the use on the DBX I am not sure if that comes with the 80-8 but I do not have that cable , ( though I may have some plugs) but I am not sure whats on the back of the 80-8
