Subject: HELP!

Sorry if this is misposted, but I have already tried elsewhere and gotten
nothing but sympathy.

I am now the mystifed owner of a Shugart SA-1004 and SA-1400 8" hard drive
and controller, extracted complete from a Xerox-820IIH system (hence 
comp.os.cpm).  I have no Xerox 820, at least not running, but I have both
an 8" floppy controller, which the SA-1400 will allegedly talk to, and an
ST506 controller. According to some very old docs I got, back when the 
first 5.25" disks were shipped, the ST506 is "similar" to the SA-1000 series
interface, which implies to me I can hook this puppy up to my HD controller
as well.  For various reasons, the SA-1400/FDC solution is better, but I have 
NO DATA except a glossy brochure ca. 1980 on the "entire" Shugart family, up
to the SA-450 and SA-850, plus a glossy on the controller.
I also have an SA-850 that thinks it is a SSDD drive.  How do I convince it
it is a DSDD?  It came in the enclosure with the HDD, and the HD at least 
looks to be brand new, still with the shipping blocks in place.
What have I got, where can I get ANY docs on it, or should I just use it 
to replace the desk leg?
Thanks in advance.
