Hi folks, I'm looking for either an HP-1600A manual, or for some kind soul to give me a few pointers on how to use the 1600. I got it without the manual; but I do have all the probes. My main questions are: a) what do the "Qualifier" switches do? b) how do they relate, if at all, to the "Trigger Word / Map Locator" switches? c) how do I trigger on various patterns (if I can)? d) some explanation of the "Trigger Mode", "Sample Mode", "Table", and "Map" switches. e) any other general operating tips would be appreciated. I'm posting to this list because I figure a few people out there use these things for their antique computer collections; I certainly plan to use mine to restore my PDP-12 :-) http://www.parse.com/~museum/pdp12/pdp12/restore.html I intend on using it with a "clothes-pin"-type 14 and 16 pin adaptor to check on the operating state of various ICs...
