Subject: Query: Hard disk upgrade for Kaypro 10

With the current trends of inexpensive hard disks it seems quite worthwhile
to upgrade an older system. I'd like to find out about the possibility of
adding more disk storage to a Kaypro 10. The options are:

1. Remove the present 10Meg disk (after dumping it on lots of floppies
   of course). Replace it with a 20Meg or larger disk. The physical
   requirements should be similar. The only changes I envision are
   modifying the BIOS and re-assembling and re-installing the system.

2. Keep the current 10Meg disk. Add an external 10M, 20M, or whatever
   size disk with its own enclosure and power supply. Here I'm not sure
   if there is another port that can connect to an external disk. The
   disk controller board should be able to control two drives though.
   The software mods should also be quite similar to 1 above.

Questions:
1. Has anybody done such an upgrade? If so, what are your trials and
   tribulations?
2. Are the schemes above possible or are there other options?
3. Can the disk controller in the 10 address more than 10Meg?

The machine's warranty had long expired and neither Kaypro nor dealers
are very interested in supporting the 10 anymore so an upgrade such as
this should not make the system any less maintainable than it already is.

Thanks for any comments or suggestions.
