Re: Received Apple SCSI card rev C. I need an opinion

[Lockar <lockar@nowheretobefound.com>]

      Take a look at where the drive connector is on the back.   The
termination is done on these type of drives.  If it terminated you
should see 3 brown (normally color but they can be another color)
resistors.  If they are there the drive is terminated, and not and you
just see holes then the drive is not terminated.

    I hope this helps.
