Alpha-Top Green756
The Alpha-Top Green756 is a generic/ODM laptop. It was sold by Micron as the TransPort Trek, and possibly some revisions of the VLX. NEC also sold it as certain models in the Ready 200 and 300 series of laptops (with others being Green755s).
Unlike most other Alpha-Top laptops, the Green756 did not have a generic version and none were sold under the Green756 name. We know Alpha-Top called this one the Green756 because that is the model number printed on the motherboard.
The Green756 is pretty much an enhanced Green755. It supported Intel Pentium MMX Tillamook and AMD processors, included a USB port, along with many other improvements.
CPU Support
The Green756 shares the same CPU daughtercards as the Green735. There were two options. First, a module with a soldered Intel Pentium MMX Tillamook CPU on it, either 233 or 266MHz. The second option is a daughtercard with a standard Socket 7 socket on it. Green756s with the socket 7 option all shipped with AMD K6-2 CPUs, possibly supporting up to a 400MHz chip. This is unconfirmed. Intel CPUs may have also been supported, but this is also unconfirmed, and none shipped with them.
RAM Support
The G755 has two 144-pin RAM slots that support EDO RAM modules. The maximum memory capacity confirmed to work is 128MB with 2x 64MB modules. It may or may not support more if you can find 128MB EDO modules, which are a bit rare and expensive.
PSU
Unlike the Green755, the Green756 uses a standard barrel jack. This should make it easy to use an off-the-shelf supply to power one.
HDD Adapter
Avoid buying a Green756 that doesn't come with the HDD caddy and adapter. Like most laptops, while the HDD itself is IDE, it plugs in through a proprietary interposer/adapter that's specific to this laptop. If it doesn't come with the adapter, you won't be able to plug in a hard drive.
Drive Modules
These laptops have a single modular bay, that can have either a CD-ROM or Floppy module installed. A rare "L-bracket" adapter exists that allows a second drive to be connected externally.
Batteries
The Green756 uses the same batteries that the Green735 uses.

I don't have the CPU switch block configs for this model at this time, however, they're likely the same as the Green735's are if I had to guess. See the G735's configs here.
The above configs are only for the Socket 7 Module. If you have the Intel Tillamook module, you don't have to worry about switch block configs.
Common Faults & Maintenance
Brittle Plastic
Like nearly ever 90s laptop, the plastic on the Green756 is quite brittle with age. Display hinge failure is quite common on these due to plastic cracking. The hinge covers also often go missing (even the one in the photo I have on the main page has both missing). Handle with care.
