[vcf-midatlantic] Which Amigas support 1.44MB/1.76MB floppy drives?

Hey there - I was just curious which Amigas (and KS/WB versions) support 1.44/1.76MB floppy drives? I have an HxC emulator that can support 1.76MB ADF files, and I know some later Amigas can support this format, but it doesn't work on my Amiga 500, at least when booted to KS/WB 2.0 or 3.1. I believe the floppy controller on the Amiga is part of Paula, so what else changed that allowed this format to work? Would a stock 1200? Thanks! John
