I'm trying to daisy-chain a Mac 140Mb SCSI drive on my Microbotics
HardFrame controller.  I've never done SCSI daisy-chaining before, so
I'd like to know:

   1) Is the daisy-chaining direct (ie: do you just plunk another
      drive onto the same cable with the same pinouts?)?
   2) The connector is different on the Jasmine (a 55-pin Centronix-like
      connector) than my original drive (presumably 'cause it's a Mac
      drive which I've heard is different).  How do I make a cable
      for the Jasmine (pinouts?)?
   3) Has anybody ran into any weirdnesses with the Jasmine drive when
      interfacing to a HardFrame?  When I installed my first drive the
      HardFrame polled my Miniscribe drive and I could use the defaults
      (for # of heads, interleave, etc.).  Is this a SCSI standard thing?
      The reason I ask is that the Jasmine drive has a jumper to select
      which SCSI device it is which I don't recall having to have to set
      on my Miniscribe, but I could be wrong.

Thanks for any info.
