This was me recently so I decided to develop a way to write 5.25″ MFM floppy disk images for a number of platforms using a Commodore 1 floppy drive. Most commonly, you’ve picked up a new computer and it didn’t come with any boot floppies and you don’t have access to a “tweener” PC (a PC that bridges the gap from the modern era to the 8-bit era, usually with the addition of a 5.25″ floppy drive). Today, there’s a need to create new floppies from disk images that you’ve downloaded. This was a big step forward in compatibility at the time. Programs like Big Blue Reader and Super Sweep 128 allowed you to copy files between Commodore format and MS-DOS formatted floppies. GCR (Commodore, Apple, etc.) and MFM (common on CP/M and DOS platforms).īut so far, this has been limited to formatting disks and manipulating data at the file system level. This is because the 1571 floppy drive can read and write two types of disk encoding schemes. If you have a Commodore 128 and a 1571 floppy drive, you might already know that you can read and write certain CP/M floppy formats while in CP/M mode. Did you recently get a new MS-DOS, KayPro IV, or Osborne 1 computer but no boot floppies?
