Leo,

One thing I immediately noticed when I replaced my CSA setup with the
Hurricane is that numerous parts (e.g. connector, capacitors, etc.) on the
Hurricane CPU and RAM boards are HIGHER than the plane of the 5 support
posts (of the A1000).  Thus, when you tighten down the RFI shield, bizarre
forces and torque are applied to the Hurricane setup.  SOME parts on the
Hurricane (like the RAM's jumpers) "could" actually make intermittent
contact with the underside of the RFI shield causing one's system to emit
vulgar noises while flashing bright blue, green and yellow.

Thus, I've pulled the RFI shield and have been carefully using an Adel
nibbling tool to remove metal in the area above the Hurricane cards; to this
modified RFI shield I intend welding a flat piece of metal that'll be in the
same plane at the top of the power supply and the internal disk drive.

Also, you "could" be experiencing intermittent shorting to the WCS
daughterboard (even if you place plastic spacing sheets between the WCS
and the Hurricane.  What I discovered to be ABSOLUTELY ESSENTIAL was to
trim *ALL* the leads on the "topside" (solder side) of the WCS and on the
bottom (solder side) of the Hurricane since some of the leads of the IC
sockets and other components WILL pierce insulation.

If you're coming to the FAUG meeting Sept.6 and don't mind waiting until
after dinner (~1AM), you're welcome to see my setup; I'm 4 miles further
south than the FAUG meeting place (and adjacent to I-280).
