Hello, I've got an old hard drive that I'm looking for information about.

Here is what I know...

AT&T label says...
	KS-23054, list 1
	36 megabyte drive

CDC label says
	MN  BJ7D5-A
	PN  77731604
	SN  3071592R
	Lot 0-8439

It is either a 94448 CMD or a Wren I.  Anyone know the good stuff, such
as 
|       CAP   = CAPACITY IN FORMATTED MEGABYTES
|       CYC   = MAXIMUM NUMBER OF CYLINDER
|       H     = NUMBER OF DATA HEADS
|       RWC   = START REDUCED WRITE CURRENT
|               IF IT'S = CYC + 1 THEN IT IS NOT USED
|       WPC   = START WRITE PRECOMP
|               IF IT'S = CYC + 1 THEN IT IS NOT USED
|       ENC   = ENCODING METHOD R=RLL, M=MFM
|       RATE  = TRANSFER RATE IN MEGABITS/SEC
|       ACCESS= AVERAGE ACCESS TIME
|       SPT   = SECTORS/TRACK X 512 bytes
