[SunHELP] question about a raid chassis.

[Bran Tregare]

I have an opportunity to get a sun raid chassis cheap, it is a 540-3085 
chassis, it's kind of purple colored and has 7 drive slots.  it uses SCA 
drives, How can I tell if it's Differential or SE?  there is no marking on 
the circuit board in it :(  and is $50 a good price for it?

  on another note, I have a couple 370-2435 Differential raid controllers 
for some sort of raid chassis, they are about 8" square.  they are missing 
their ram. it looks like they do 6 channels, looking at the Symbios logic 
SCSI chips (there are 6 of them)
