Using raw magnetic flux data captured with David Gesswein's MFM emulator, evil Claude was able to figure out that the format on this miniscribe 3425 was a nonstandard RLL 2,7 with swapped codewords, a nonstandard CRC seed (0xcc7d), and a 48-bit ECC polynomial (0x1181814503011).

Very cool how is it! I have been thinking to get one. My first "blackberry" was this form factor and I wish I could emulate the network so I could use it 😭

Casio camera watch I got in Japan some 25 years ago. I found the watch a few years ago in a bin and downloaded this picture over Infrared.
