The 1650 series is much older, but good units are still worth a couple of thousand. Actually, the frame and base unit is the 16500... the protocol analyser module that goes with it is the 16550 (basically, a HP Unix box that does data analysis on the megabytes of data captured by the LA). Ob2600: anyone want to see a CodeWarrior for Atari 2600? Not that we would make it, just a cute thought. (Just trying to imagine C++ code running on the 6507 with 128 bytes of RAM gives me chills!) -- Benjamin L.
