BTW, I did try a 7A22, a 7A26, and a 7B85 in the plug-in slots last night.? Readout was a bit
grainy, and it
was impossible to get a stable trigger on the calibration squarewave except at the highest
amplitude, a
few volts.
Since the 7B80/85 use +5V it is not surprising that they don't work properly if your 5V is screwy.
