I have an '83 Kaypro 4 (no graphics or internal modem).  It came (new) 
with 2 full height DSDD (TANDON100-2's?) drives.  When drive B died 
(became un-alignable) it was replaced with a 1/2 height PC type drive.
The same drive on the Kaypro will format a disk to 390K and on a PC it
will get 354K (360K if K=1000).  I have used a cpm based kit on the
KAYPRO (kit has a DYSAN alignment disk) to align a drive which was then
used in a PC with no problem (yet).  Just set the drive select jumper
correctly or your machine and make sure that the last drive on the
cable is the only one with termination resistors installed.
