Costronic CV-27PD v3 PCI Bus Debugger debug Dual-LED Single Step Trace card
$135.00

Very rare Debug card for use with PCI based computers from around 2002. This card should allow you to halt and single step through instructions, showing full address and data bus value status. I\'ve plugged it in and the thing runs, blinking lots of lights, showing POST codes on the side display, but i don\'t have any instructions for it and don\'t really know how to make it halt and step.
This thing was new-old-stock and I actually only opened up the packing just before Christmas to test it out. It comes with a spre switch and had the Flash rom which i installed onto the sub-board.
