Needle cards:
-------------
A needle card is developed for the ATLAS project. Due to some
bugs the card needs a second iteration. This gives us the
possibility to propose some changes/enhancements so that the
card can be used for our projects.
Suggestions:
                * connect every power needle to the corresponding
                  power ring
                * add power connectors (instead of using the Samtec-
                  plug for the power connections)

CMOS6SF user meeting:
---------------------
* U. Trunk has made up a list of future submissions
  for both projects.
* U. Trunk shall pick up information about Monte Carlo
  simulations with the cmos6sf design kit.

OTIS:
-----
* The DACs implemented on OTIS1.0 can not deliver enough current.
  DACs on OTIS1.1 will be buffered.
  The currents needed are:
        Threshold       ASDq: I [uA]
        low                200
        high               600

        Threshold [V]   ASDblr: I [uA]
        0                  0.8
        0.12               1.0
        0.3                0.15
        0.35               1.58     this is about the standard level
        0.4                1.7
        0.45               1.83
        0.5                1.94
        1.0                3.14
        1.5                4.48
        2.0                5.72
        2.5                6.9
        3.0                8.2
        3.3                9.2
        3.5               18.5
        3.6               53
        3.75             127
        4.0              277
        4.5              600
