Mediatechnics Hardware Lines:

The current models are called Fusion, older ones are called Impact or Pact.  We discuss only the Fusion below. 

Two major varieties:

MX and PX

MX hardware (e.g. http://www.mediatechnics.com/pages/fusion4pcdvd.htm ):

- Largest total load capacities, up to 900 discs.

- Has a separate drive or printer riser bolted onto the right side of the flat platform.

- On the opposite side of drive column (left side) the equivalent space is used for the optional fourth disc stack

- Has four (or three if printer is wide) disc stacks, a disc output spindle and a tiny reject spindle.

- Comes in 150 and 225 disc stack heights with a max capacity of 600/450 (short four vs. three stack) or 900/675 (tall four vs. three stack)

- Always has a place for a keypad/LCD in front of the reject spindle, whether or not the unit includes said items.

PX hardware:

- Lower capacity (up to 250 discs), but somewhat faster average disc swap time speed due to smaller total distances travelled per disc swap (esp. type 2).

- More compact form factor.

- The drive/printer riser is integral to the case/platform and exists across the entire back of the unit.th

PX hardware type 1 (e.g. http://www.mediatechnics.com/pages/fusion2pcdvd.htm ):

- Maximum of two drives on right side

- Disc stacks are rotated up against the left side of the rear hump and placed asymmetrically.

- This configuration leaves space for a keypad/LCD in front of the reject spindle, whether or not the unit includes said items.

- Same command set as MX above.

PX hardware type 2 (e.g. http://www.ripfactory.com/images/resources/MT4PCwithlogo.jpg ):

- Maximum of four drives, two on each side.  Typically installed one on each side or two on each side

- Disc stacks are place symmetrically with two close to drive input stacks, a central output spindle closer to the drives and one or two tiny reject spindles under the drives.

- No space is available for LCD/keypad.

- Requires different command set than MX due to specifying which drive locations to pick or place.

(notes will continue later)

A note on MF-Digital units similar to the above:

Contemporary MF-Digital machines are probably the same hardware platform(s) and at some later point I will include information on matching up the models to the MT models.  Early comment is that from what I have seen the contemporary "Director" units are MX and the contemporary "Scribe" units are PX-based (maybe only PX type 2)...unless more than four drives when they are also MX-based.

There does seem, however, to be a divergence in the controller boards used by Mediatechnics and MF-Digital, even if the robotic hardware (cases, motors, sensors, pick-arm and tower assemblies) are the same.

I believe they used to all share the CD-Robotics -> Elliptical Systems geneology, but I am not clear if the Yurex boards are the next step or a fork in two directions (and there may be even another board type out there).  The command sets are similar, but more recent boards may require so tweaking ot scrits using the ULCLI.
