Up for sale is a Vintage Marconi Instruments Logic Analyzer 5500. This unit has been tested for power and keyboard functions only. I do not have the software disks, probes, or expansion cards. As shown in the auction photos, the handle is bent, though it still locks and moves to position as it should. This is the only significant damage to the unit. Overall, it is in excellent shape. Please let me know if you have any questions or concerns.
