Rodland it is :-) Loved that one.
 
I guess you ripped off old guts and put inside standalone Vampire V4?

  I would call an Atrix dock. I believe it had made appearances before :)

Its not bad, its nice cheat. Its juts "smartphone laptop frontend", so Vamp can be somehow hooked to it.  I am not sure could you real take a standalone and astrix easily around ... :-( Unless we shrink Vamp to mimic Motorola tablet >:)
 
  AT&T made for Motorola Android device, an interesting unrelated of Amiga unrelated US product :)
 
  Something like

  Laptop dock for the Motorola ATRIX 4G for a more interactive computer-like experience from your smartphone
  Large 11.6-inch screen and full keyboard make it easy for you to browse and work
  When ATRIX 4G is docked, the webtop application opens with full desktop Firefox web browser with support for Adobe Flash
  Super thin design and weighs just 2.4 pounds--easily slips into your bag just like a laptop
  Internal rechargeable battery provides up to 8 hours of use
 
  Customers are quite satisfied

I believe nothing but that standalone can use it as power supply, keyboard and mouse and monitor. But then again quite enough.

Or it's just an old laptop running UAE... :D

Gunnar, please enlighten us... :)

  It's a motorola Lapdock designed specifically for the Motorola ATRIX phone line, there was a few iteration made. It's a common thing for people to attach it other mobile devices, Raspberry Pi's and other single board computers to it.

Zombie + Vampire :)

The Laptop is designed as "empty"
The Laptop has Monitor, and Speaker, and Keyboard and the battery -
but its designed that the "computing" is done outside of it.
This means you need to attach a "computer" to it on the back.
The V4-Standalone is plugged into it on the back.

The battery of the LAPTOP powers the V4-SA.
This gives you a mobile AMIGA.

@GUnnar: So, how do you connect the V4-SA to this Lapdock? Micro-Usb?

@Gunnar so just the USB connection alone is enough to power the Vampire and send the video and audio to the lapdock?
 
  I've got one of these and from what I remember it has Honeycomb installed and the phone acts as the CPU. How do you bypass all of that and get the Vampire to drive it?

Edit: can you show a picture of the rear so we can see the connections?

I suppose LapDock is used for connection and that behind is Vamp as board connected to it

Curious whether the touchpad works. Often with these units the touchpad doesn't work when hooked up to anything other than the intended device.

Nah, its double zombie.
We just abuse the dock connectors faking Vamp to be intended Android phone.

  laptop, without the laptop
What the laptop dock--or, Lapdock--is, in effect, is an extremely well-constructed dock for the Atrix phone, adding a long-life battery, a keyboard, a large touch pad, two USB ports, and a pair of stereo speakers. It looks like the Cr-48 Chrome OS laptop, and or even a sleek thin-and-light. At 2.4 pounds it's easy to tote, and has a sturdy feel when the lid is closed.

But it's not a standalone machine: The Atrix needs to be plugged in for the laptop dock to work. The good news is that the transformation is seamless and hot-swappable: Plug it in and the dock boots up. Unplug and the phone's back in your hand, ready to go.
-------------
Motorola Atrix Lapdock is a docking station (dock) for Motorola Atrix smartphones, which aren't on the market any more. Remaining Lapdocks can now be found much cheaper on ebay and similar sites. Atrix Lapdocks provide a latop-like features - they have a battery, keyboard, touchpad and a screen.

Atrix Lapdocks are now an interesting piece of hardware for Raspberry Pi and similar mini PC users. The docking station allows us to create a laptop-like Raspberry computer. The battery in the dock provides power to the mini computer allowing "mobile" use.

Lapdock consists of 36Wh rechargeable battery, 11,6" screen, a touch pad, keyboard, stereo speakers and two USB ports. It connects to the Atrix smartphone or other devices via micro DIGITAL-VIDEO and micro USB. The USB provides power for the device.

Connecting Atrix Lapdock to a computer
On the back of the dock you can flip a panel to reveal a Micro DIGITAL-VIDEO and Micro B USB male ports. Those were used to connect Atrix phone to it. To connect the dock with Raspberry Pi or other computer we have to use some cable magic. The ports are male and they are close to each other which makes it harder than usual. Also the Micro B USB provides power as well as keyboard/touchpad functionality. That worked for the phone, but for computers we will have to split the power lines from the keyboard/touchpad lines (even if you don't plan to use the power from the dock).

DIGITAL-VIDEO connection is quite straightforward. We need a Micro DIGITAL-VIDEO female to DIGITAL-VIDEO male adapter and a double female DIGITAL-VIDEO adapter. That allows us to connect the dock with any DIGITAL-VIDEO-enabled computer via normal DIGITAL-VIDEO cable. There is a big chance that you may get a incompatible DIGITAL-VIDEO cable - some cable may work with your TV or normal computer but will fail to work with the dock as they miss DDC/CEC pin grounding implemented as separate from all other pin grounding. A good DIGITAL-VIDEO cable should turn a white led on on the dock touchpad. The bad ones won't and you won't get any signal on the dock screen.

Testing multiple non-bagged DIGITAL-VIDEO cables in shops I found that only two similar HAMA branded cables work - 00011959 and 00011955. They are quite cheap and you can see them on the picture below. HAMA website shows at the moment different pictures which may be a bug or a change in the cable (which may be a problem). Few other tested HAMA cables did not work!.

Compatible DIGITAL-VIDEO HAMA cables
As the USB/DIGITAL-VIDEO are close to each other you may be forced to cut some plastic from the adapters. A hot blade is very good at melting-cutting the plastic but it should be done carefully (hot blade is a dangerous tool) and with some air flow to blow the smoke from melted plastic.

There is also a thin plastic cover around the USB/DIGITAL-VIDEO ports that can be taken off. That gives few mm more for the adapters.

Docking ports on the back of the lapdock
Micro B USB and Micro DIGITAL-VIDEO ports
USB connection cable
To make the keyboard and touchpad working we have to use the micro USB. It also provides power which usually isn't handled correctly by computers and similar devices. Thats why we have to split the power from the input devices. Raspberry and similar low-power mini PCs may use the power lines to get the power. Other that can't will use only the input devices lines. In both cases we have to split some USB cables and solder correct wires.

In case of Raspberry Pi ver B it's possible to use single USB to power the device and provide touchpad/keyboard connection. For those devices a single female micro B USB to male USB cable would do the trick - no cutting or soldering.
We need two USB cables - a Micro B extension cable (may be hard to find), and a standard male USB cable. If you don't plan to use the power try to find a female Micro B USB to male USB (if it exists).

Cut the Micro B extension cable in half and remove the outer isolation on both half. You will see a 4 thin wires in color isolation. Remove the isolation from those wires too.

Solder white and green wire from the female Micro B USB cable part with the white/green wires of the USB cable. If you want power solder red and black wire with the second half of the micro B USB cable. The USB plug provides input devices and the micro USB provides power.

Lapdock usages
The Lapdock may be used with various mini PCs like Raspberry Pi, Odroid and many others. It can also be connected to normal PCs and laptops providing additional screen. Some tables, phones or HDM-sticks with Android can be connected too (although not everyone of them may support keyboard and touchpad).

How it works
The power is turned on when you open the lid (it may vary depending on dock model) and turned off when you close it. When the system boots the screen should catch and display the DIGITAL-VIDEO signal (including sound
