[cctalk] Re: looking for HP 1640B GPIB info

You could try https://groups.io/g/VintHPcom/messages https://groups.io/g/HP-Agilent-Keysight-equipment https://groups.io/g/logicanalyzers/messages I couldn't see it on BAMA of K04BB but there are others. The other possibility is to pull and read the ROMs - sometimes HPIB commands show up as literal text.
