I set the 1581 as drive 9. There are a bunch of steps involved but that’s my old-school way. good to know, but in this particular case I was just interested in examining both the gcr-encoded and decoded bytes of various parts of a 1541/4040 track as I'm making my own version of an IEEE-488 single floppy drive, so I need to see if it's producing the right bits at the right time (erase intervals etc...) I use cbmlink from linux box with a real parallel port connected with a PC64 cable to C64/VIC/PET machines' user port to transfer single files or D64/D82 images (for the D82 I have the SFD-1001 drive). If I need better speed, I can write an entire D64 image with the greaseweazle using any old PC 48tpi drive. Unfortunately 100tpi drives with a shugart/PC interface are extremely rare so I can't use the greaseweazle for the 8250/8050 images or even inspect an 8250-formatted disk at flux level.
