I am considering purchasing the H3D 39Mp and need to know if I can use the digital back on my Sinar 5x4, Mamiya RZ 67 Pro II and on my microscope. Does anyone know if there are adaptors for these three items? Does anyone have first hand experience using the H3D back on other cameras?

The digital capture unit (ie. digital back) of the H3D-Series are quite useful on a number of large format and technical cameras. Using the back on a Sinar 4x5 is not a problem, as there are several back adapters available (Kapture Group, etc). To use an RZ67 with H-mount digital back, it would require Mamiya's RB67 film back to RZ67 body adapter, (discontinued RZ Pro Adapter G), along with a Graflok-style digital back adapter. Its possible, but kinda expensive. I have not used the H3D digital capture unit on a microscope, however I would assume it would require the use of the H3D body to work properly. I am assuming your microscope does not have an aperture & shutter, and / or the ability to sync directly with the back from the H3D.
Keep in mind, the H3D digital capture unit can be externally sync'd with a multitude of different cameras. The back has both sync-in and sync-out connectors, specifically for this type of application. Your camera options include various cameras from Sinar, ARCA-SWISS, ALPA, Silvestri, Horseman, Toyo, etc.
The H3D digital capture unit works wonderfully on the ALPA 12-series cameras (including the XY). I personally own and use an H3D-39, as well as an ALPA 12TC, and find the two to be a great combination. The current lineup of ARCA-SWISS 6X9 (Monolith & Misura) cameras are also a nice platform for the H3D digital capture unit(s). I just configured a rather old Sinar P2 4x5 with an H3D-39 digital capture unit, along with a recently converted Kapture Group sliding adapter (converted from Hasselblad V-series to H-Series).
Depending on your application, older view cameras don't necessarily offer the precision for shooting with super-wide lenses, and keeping the front and rear standard perfectly aligned. It just depends on what (and how) you shoot.
Another recently added feature for the H3D digital capture units is being able to draw battery power from the new ImageBank-II. With the back mounted on any camera other than the H3D body, you can supply power to the back via Firewire 800, either connected directly to a computer running FlexColor, or connected to the ImageBank-II with a L-type Li-Ion battery.
