fun fact: Commodore Amiga floppies used 32bit XOR checksum = 3% of undetected two bit errors!! http://www.techtravels.org/amiga/amigablog/?p=280 http://www.tec

fun fact: Commodore Amiga floppies used 32bit XOR checksum = 3% of undetected two bit errors!! http://www.techtravels.org/amiga/amigablog/?p=280 http://www.techtravels.org/amiga/amigablog/?p=280 This is probably because Amiga didnt have real hardware floppy-disk controller, just a general IO (CIA) chips, and read raw serial datastream into ram, all the decoding was done in software. Similar to Apple II 2x 8bit XOR checksum.
