Nibblers can, but how do thet do that? They can't, they just try all combinations and see if they read correct sync marks. I think the most advanced nibblers can "detect" the speed of each sync and the following data, but I think it's impossible to guess the speed of a single byte, since you don't know what the correct value is. Maybe Markus Brenner knows more about it, he disassembled Burst Nibbler 1.9 and created a PC-based nibbler based on this. But I think speed detection is not done yet. www.brenner.de should get you to him ;-) Damn, no, broken link. arnold.c64.org/~minstrel works.
