For those with digital backs for Mamyia and Hass' analog bodies how does the back know to turn on when the shutter is tripped to take a picture?

The Mamiya AFD has the circuits built in to trigger the back to record. The Fuji 680 requires an interlock device to trigger everything at the right time. If I remember right there is a pc connector on the Phase One back for that, I dont know for sure but it might could plug in to the flash contact on a shutter and activate on firing.

Some older medium format SLRs have no means for the body to tell the back to 'wake up and shoot'...some rely on a dual (split) cable release. Much newer medium format SLRs have an electrical protocol that allows the body to coordinate with the back.

Whenever I read the title to this thread I wonder if it is a throwback from the 1960s .

...except it's missing the bit about tuning in and dropping out. Now I'm wondering if Timothy Leary ever carried around a Leica. I know those folks in the Hog Farm were quite tech savvy with their bus and all the electronics.
