Subject: Re: hard drives for Osborne I and Kaypro II

  One option is to use a SASI host adapter that piggybacks into a Z80
socket (i.e., the Z80 is pulled out, the daugther board is plugged
in, and then the Z80 is plugged into the daughter board). Xebec (the
hard drive controller people) have such an interface detailed in their
manual for the S1410 hard drive controller. All you would need would be
the host adapter board mentioned above, a copy of the BIOS so that you can 
add the mods so that CP/M can recognize your hard drives (you do have a 
copy of your BIOS, don't you? :-> ), a disk controller board (i.e., 
Xebec S1410, Adaptec-4000... a shugart surplus lookalike is available in the 
$80 range), a power supply for controller and drive(s) (PC-type supply, 
perhaps) and appropriate signal cables.
  Another option is get one of the hard drive adapters sold by some of the
advertisers in Micro Cornucopia (Emerald Microware?). These are pricy for 
what you get, however. It may just be cheaper to buy a used Kaypro-10.
