I have the entire 1325 manual (at home .. sigh :-(  ) but i do remember the
track / cyl layout ..  
this is :

	8 heads
	1024 cylinders
	17 sectors / track
	512 bytes / cyl

	(obviously the last two depend upon your controller .. but i would
	 not reccommend using RLL on this drive .. stick with MFM.)

	write precomp .. not needed - set to 1024
	reduced write current - not needed - set to 1024 (note that as i 
		remember this line is not implimented on this drive so 
		the setting is meaningless)

If i remember i will look tonight about the jumper settings.  If you
call Micropolis they will send you the manual on the drive free of cost.
Sorry .. I don't have their address here either :-(.

I will tell you that this is a nice drive. I picked mine up only slightly
used ( by a little old hacker who only programmed on Babbage's birthday :-)  )
and it has work flawlessly for over a year.  before you install it you might
want to put a damper on the static pickup that you will find sticking out
of the circuit board.  After a while mine began to whine .. real aggravating!
I simply put a small piece of foam tape from one end of the pickup to the
circuit board which seemes to damp out the high frequency squeak!

Good luck and have fun. 
If you want to converse more you can email me via cadre!pitt!darth!liber
or land line 412-367-7308 .. feel free to call me after 7:30 any evening
since i am usually home .. if you get my answering machine i WILL call you 
back.
