I have one running on my BBS.  Great drive!

It is a standard ST506/412 drive, not a SCSI or ESDI drive.

Yep, I use an Adaptek 4000a with this drive.  You can use practically
any 506/412 drive on an Adaptek.

You need a controller.  Like I said, it does not have an embedded
controller.

The ICD Host Adapter I use comes with the DMA cable.  However, you will
have to get a 50 pin header-header cable, 32 pin card edge-header cable,
and 20 pin card edge-header cable.  The "10 and 17 pin card edge" you
referred to are really 20 and 34.  Look at BOTH sides of the card.  Also
pin 1 on each card connector is labeled.

>5) Theres a wire trailing off this behemoth, is this a grounding wire??

I had no wire hanging off mine.  Is it connected to the housing, or the
circuit board?  Also, the bank of four "pins" on the side of the drive
are ID pins.  However, pin 1 (if I remember) is on the right hand side.

>thanks to everyone who can help me..

You're welcome.
