o TAB/GAB crate
  - 2nd TAB/GAB crate being assembled
  - will repair short in 1st backplane when 2nd is finished
o TAB/GAB firmware
  - (still) updating some TAB firmware to aid in system simulation
    . first stage ready to test
  - will start coding a few example and/or terms as soon as this is
    tested



Saclay: ADF/SCLD (D.Calvet)
----------------

o SCLD testing finished
  - used standalone version of SCLR mezzanine
    . slightly different firmware than cards in D0
  - no problems found: timing ok to ADF
  - purchasing components to build 2nd SCLD board
    . will assemble after current board has been tested w/ ADF v2
  - will send board to Dan in the next few weeks


MSU: ADF v2 (J.Biehl)
-----------

o done with pal firmware
o layout now integrating all the parts of the board that have been

o will need 160 pleated foil cables + spares
  - have ordered 9 (in early June)
  - received these last week
  - Johnny Green was not happy with pleating
  - sent back to company - should be back next week
o schematic for wiring for all components of BLS-to-ADF system is now done
o 40 patch panels
  . 32 TT cables each
  . 4 pleated-foil cables out
o Schematics for paddle boards done
  - should be able to test by end of Aug / early Sep
o Cost
  - 160 p-f cables
  - 40 patch panels
  - 80 paddle boards
  - +10% spares
  - cost est done: $35K (+10% spares)
  - will try to build 5% system for prototypes
o build mock-up of cabling at back of ADF crate
o will start looking at signals from splitters as soon as components
  start arriving 



Fermilab: TWG (S.Rapisarda)
-------------

o more details on web site
  - http://www-ese.fnal.gov/D0Cal_TWG/
o Commercial System - designed in consultation w/ Dan
  - controlled by Linux computer
