How can I convert .DSK files to real TRS-80 floppy disks?
There are several possibilities: (A) One way would be to transfer data from your newer computer to a real TRS-80 through its serial port or printer port. That may be the only way if you have a Model I, because a stock Model I can read and write only single density, but many PCs cannot deal with single density (see topic [12]). However, I don’t know of any software for transferring data to the TRS-80 Model I through a serial or parallel port. (Kermit did exist for the Model 4, and you may be able to find XMODEM or the like, but I can’t help with them.) (B) A faster and more convenient way, if you can get it to work, is to write the disks in a PC with a 5.25-inch floppy drive. If you have Linux on your PC and your disk is a standard double-density format (40 or 80 tracks, 1 or 2 sides), you can use the programs trsfmt and diskdmp by Tony Duell, available from http://tim-mann.org/trs80/trsdsk.tar.gz. See the documentation included in the tar file. If you don’t understand what to do with .
