Hi Graham,
It is a NN that can be run on CPU. It is a smaller version of the net a 12x128 compared to 20x256 used when run on the GPU.
The Scorpio CPU version using 12b net beats Scorpio-Alpha-Beta so you might be surprized.
Here are simple instruction to install a CPU NN version of Scorpio that I posted elsewhere
==============
There are three steps:
1) Choose a directory without spaces in the path and download and put install.bat there.
Please download install.bat fresh from this link. It is also recommended to do this periodically whenever you want to upgrade
as I might change stuff there.

Also, make sure there is no "Scorpio" folder in the install path, or remove all of them since you do not need older versions.
2) Run install.bat without parameters on the command line.
It will download necessary files (networks, cudnn etc) and extracts and install them.
Then, It will make a "test run" when it finishes installing to confirm it is working properly.
3) Then install scorpio.bat as the engine in your favorite GUI as a UCI or xboard engine.
That is it! You do not need to edit scorpio.ini if you follow these steps.
To install 6-men egbbs (completely optional as the above steps come with 5-men) and do other advanced stuff,
read the installation document

=======================
Let me know if you need help and I will come to your server and help you live, but I think you will be able to do it yourself.
