Many years ago, I bought one of these: http://www.pctestinstruments.com/ 34 channels and a great app (though very light on the decoders)
There are of course cheaper options nowadays, such as the open bench logic sniffer: http://dangerousprototypes.com/docs/Open_Bench_Logic_Sniffer That is 16 bits, but there is a buffer wing that gives you another 16 channels. These are true state analyzers meaning they have real clock inputs and qualifiers. From: Brian K.

And my Rigol has 4 channels... I should be able to watch the entire bus at once. Though, maybe not usefully, with the control, data, and address lines in 3 different logs from 3 different devices that probably cannot be accurately synced up accurately enough. -- bkw
