Does anyone know if the Sony Double cassette Deck TC-V701 is compatible with the 505 seies system?

Having found a TC-V701 for sale on eBay, I'm wondering if this twin deck machine will work with the later LBT-D505 & TA-D505 stacking system. Both use the flat ribbon cables to connect the units together, but, whilst i have information on the 505 (and 707) series, this doesn't tell me whether the earlier decks, such as the TC-V701, can be used with them. Does anyone know?
