Looking at the manual for the Z80QT pod and the schematic I think I am getting an expected result. I hooked up the pod and hit BUS to run the bus test. I immediately get back CTL ERR showing 00000010 this is the HALT line. Looking at the schematic it appears HALT and INT are both tied together and pulled high. So the fluke can't exercise that line. Any way to ignore that error and verify the rest of the bus test? Oh and according the manual maximum clock frequency is 8.0 mhz. Does that mean this pod support Z80A/B/C ?

Anyone know if you can use either the base z80 pod or the z80qt pod on Mario bros? I know it uses the Z80A but I don't know what the pod is rated at.
