Very interesting !! David, would you elaborate on >> The IMI 77xx are neat looking drives. >> ( English is not my native language, and I am not sure I fully understand the implied meaning of this statement ) This is anyway a very interesting post as I am building David's interface right now ( last parts to arrive in a few days ... ) and my plans are to use it with an IMI 7720 drive !! Knowing the interface is a bit non standard and that I will have to modify "things". But, ** FIRST **, I will, I hope, make it works with a "standard" ST412 drive. --- Ce courrier ?lectronique ne contient aucun virus ou logiciel malveillant parce que la protection avast!
