What is it?

CBM-Command is a disk manager for the Commodore 64, Commodore 128, Commodore VIC-20, Commodore Plus/4, and Commodore Pet/CBM computers. It is written in the vein of Norton Commander or Midnight Commander; but, it is much simpler due to the target platforms. Each Commodore model has its own native version of the application.

What does it do?

It works on both real machines and the VICE emulators.

So far, we have tested it with the following hardware:

  • Flat Commodore 128 w/JiffyDOS
  • Commodore 1571 w/JiffyDOS
  • Commodore 1581 w/JiffyDOS
  • uIEC/SD
  • Commodore 64 (stock)
  • Commodore 64 w/JiffyDOS
  • Commodore 64 w/SuperCPU
  • Commodore 1541 (stock)
  • Commodore 1541 w/JiffyDOS
  • Blue Chip 128 Disk Drive
  • Creative Micro Designs FD-2000 Floppy Disk drive
  • ZoomFloppy USB-to-IEC adapter (w/ WinVICE and OpenCBM)

Additional testing has been performed under VICE, using the following file systems:

  • IDE64 Native Filesystem
  • VICE File System
  • VICE Virtual Drives (not True Drive Emulation)
  • 1541 TDE
  • 1551 TDE
  • 1571 TDE
  • 1581 TDE
  • CBM 8050 TDE
  • CBM 8250 TDE
  • Commodore Plus 4 Emulation
  • Commodore VIC 20 Emulation
  • Commodore 64 Emulations
  • Commodore 128 Emulation
  • Commodore Pet Emulation


  • File copying between drives
  • File renaming and deleting
  • D64 Image Writing, and Creation of Disks from Those Images
  • D71 Image Writing, and Creation of Disks from Those Images
  • D81 Image Writing, and Creation of Disks from Those Images
  • Send command to drive
  • Simple "Paging" Text-File Viewer
  • Moving into, and out of, sub-directories and disk-images
  • Configuration Utility
  • Whole Disk Copying

Development tools

CBM-Command has been developed with the following tools:

  • CC65 link -- C and Assembler compilers with linker, for building 6502-based binaries.
  • GNU Make link -- Makefile processor which builds the sources, using CC65.
  • Visual Studio 2010 link -- I suggest downloading the ISO with all of the express editions; but specifically, you need the C++ edition.
  • WinVICE link -- The best Commodore emulators available.
  • CodePlex link -- Project management and source control.


I'm looking for folks who want to adopt portions of the code, and help to make it better. If you are familiar with C and/or Assembly, or just want to get familiar with them (I had practically zero Assembly knowledge when I started this project), then contact me; and, we'll see if I can find something for you to do. :-)


  • Removed old screenshots -- need to make new ones that are representative of the current code and platforms.
