How can I put individual files onto a .DSK file or TRS-80 floppy disk?
Most of the TRS-80 emulators have programs for doing this. Read the instructions for your emulator to find out how to use them. Sometimes the program runs on the emulated Z-80 (a /CMD file); other times it runs on the host operating system (an .EXE file). Under Jeff Vavasour’s Model I emulator, the relevant program is VWRITE.EXE. Under Jeff’s Model III/4 emulator, it is IMPORT/CMD. Under Matthew Reed’s Model I/III emulator, the program is TRSWRITE.EXE and is available only with the registered version. Under xtrs and David Keil’s emulators, the program is called IMPORT/CMD (not the same program as Jeff’s).
