How to use some simple tools to preserve your Kaypro 1 Disks.
The Kaypro 1 uses a unique disk formatting system. It can be read by DOS machines, but only if you use the right tools and settings. The following information is the most basic required to perform a disk backup or write function. Specific details on what the different formats are can be found in the readme file with Dave Dunfield’s ImageDisk utility, here.
This information also assumes you know how to boot an old computer to DOS in order to run the utilities, and how to get information on/off that computer to other modern computers.
