I have an MDM Emulator and it's nice, on those occasions you are trying to read a supported drive (it supports a _lot_ of encodings, but not every single platform). Two layers - fortunately in this case, the low-level format is known (WD1002A-WX1) and that's good. I'd totally expect an MFM Emulator to be able to pull bytes off the drive. I am not a CoCo person so I have no idea what tools can be used to pull files from a raw pile of disk blocks there. -ethan
