ADC-100 using Picoscope displays small noisy square wave.
I'm trying to use an old ADC-100 on modern PCs but the displayed signal seems to be clipped below 50mV.
I noticed from an earlier posting that this is likely to be due to a missing parallel-port adaptor. The adaptor here seems to have been lost.
Is it possible to get a replacement adaptor, or (better still) what is the configuration of the adaptor? ... I assume it to be just a matter of some cross-overs within the 25-way "D" type connector.
