The documentation of the neuromorphic systems is this guidebook (on github).

Access to the neuromorphic computing systems SpiNNaker (Manchester) and BrainScaleS (Heidelberg) is possible via this Collaboratory via:

• batch mode: the experiment script is created via the Notebook here in the Collab and then sent as file to the neuromorphic compute system SpiNNaker (Manchester) or BrainScaleS (Heidelberg). The scripts are then executed and the results are sent back as files to the notebook in this Collab for analysis.
  This access mode to the systems is available since the public platform release years ago and works fine. The drawback is the slow turnaround time.
  Please use the "Lab" link in the left hand menu (note: it may take some time in the JupyterHub, until the examples are loaded, when the link is first accessed)
• interactive mode: (see the SpiNNaker or BrainScaleS entries in the left hand navigation)
