I have a Kaypro II with questionable drives - I can read and boot from the drive but cannot write to either drive and I don't have the confidence to disassemble and repair the drives.
I'd like to transfer BASIC source over to it. Unfortunately the 360kB disks it uses cannot be read by the other 5.25 drives that I have in other machines. So the only means I have to transfer a file is over serial, and again I can't write to disk to transfer a file.
So my great idea was to launch the BASIC interpreter and run "LOAD "TTY:"" and transfer text directly from a PC to the Kaypro over serial. But it fails with "File not found" after trying to read from disk.
I assumed that CP/M device files worked the same as DOS device files and I would be able to open and read the serial port like a file using the filename "TTY" (as opposed to "COM1" in DOS). But it doesn't work.
What is the fundamental understanding of CP/M that I'm missing? Shouldn't this work?
