well folks, some of us poor people in this world are still faced with the problem of floppies with only 180 + or - KB. To enhance the problem, I work on systems where disk space is measured in 3 digit MB or GB. In essence I am spoiled. I am quite happy with my world of CPM and not the least bit intrested in MSDOS.(Yechhhha!!) (There, that should tick off a few people.) If i buy a new machine it will be a multi user unix system. Since rome wasn't built in a day, and neither was my bank account, that is a future option. Meanwhile, I want more disk space. Simple enough. Next problem, I ain't the time to design my own HD system, so if anyone in the wild blue yonder has done anything or knows anything about HDs for the before mentioned machines (OB 1 or Kaypro 2) please send me the information. Thanks in advance. Bob Turner CAD/CAM Lab University of Dayton, Dayton OH 513-229-3171 ncrcae!ncrpcd!udcps3!turner

You may find out that a HD for an O-1 costs almost as much as an MS-DOS machine with a HD... not the greatest bargain in the world!

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. Dave Ritchie hp-lsd!ritchie
