[Coco] COCO FPGA

Mark already explained that he has a disk image scheme figured out (splitting the 255 images between the SD card and DriveWire). But I wouldn't care if half an SD card was wasted as long as it worked reliably. Technology moves on, and if a 2GB card costs the same as a 1GB (never saw a 720MB... 512MB or 1GB) it doesn't matter that half is "wasted" as long as it does what it's supposed to do reliably. How many of use bought 360K floppy discs and used them as 160/180K discs (whatever the 35 track was... around 160K IIRC / and 40 track single sided). Sure, some of use punched holes and made them "flippies", but I used many without doing that as prices came down.

I don't think anyone here would propose using an entire SD card for 4 floppy
images. It would be almost as painful as using actual floppy drives.

I would propose that a FAT-formatted SD with floppy disk images, and a
mechanism for 'mounting' the images would be the most sensible solution by
far. Even using the HDBDOS 255-drive mechanism would be a vast improvement
(and as I mentioned, already implemented (read-only) on my Coco).

I'm sure Gary has something similar up his sleeve...
