I have a KayPro 4 portable computer.
I need a recognizable OS for it.
I believe it was written in c\pm language.
using the Z-80 cpu.
This computer hasn't been used for 11 years.
The 5.25" disks did not retain their data due
the length of time not used.
Any help will be very much appreciated.
Hate to see it die.
Sincerely,
The Ghost...

I found this web site.

http://www.retroarchive.org/cpm/os/os.htm

They have a CD or so worth of CP/M software. Including images of some KayPro disks.

You will need to determine the format required for the KayPro disks, and copy the files onto the correct density floppies.

If you want/need them, I have 360k and 1.2M 5 1/4" drives along with blank floppies of both sizes. Shipping cost, and nominal compensation is all I would ask.

I used the overture search engine, searched for CP/M. There were a number of software archive and information sites listed.

Enjoy your "retro" hardware.
