[QuadList] Sony Flexicart system questions

[Shai Drori]

Please forgive the cross posting. Does anyone know the answers to the 
following questions about the flexicart system:
1. Can the system be controlled by rs422 or rs232?
2. If so, can it also be controlled to eject a cassette and load the next?
3. How many cassettes fit into the system?
4. Can they be mixed sizes?
5. What is a fair priced for unit without VTRs included? Used obviously
I think of using this for an ingest computer, The Samma is just too 
expensive.
