compactflash is nearly pin compatible with ATA, i had several laptops repurposed as home routers with CF cards on little adapters. I could probably dig one out and take a picture.

edit: shoot, i think i meant IDE, not ATA

Yep, my Amiga 1200 does exactly this. It’s very tempting to put it on the internet.

ATA and IDE is the same thing. Usually CF cards will just work on adapters.

Do they support hotplugging? afaik traditional floppies do and could be essential to workflows if you can avoid the costly reboot time.
