I know this is an ancient boat anchor and probably not worth fooling with, but I couldn't pass it up for $15. It came with (only) one 6-bit input module, but thankfully it appears that the pods are cheap and plentiful for these. (The lack of which was the main reason I gave up on the Tek DAS9100 I've had for many years!) I'm not having much luck finding any documentation for it, however. I've found a few application notes on the agilent site and an advertising announcement on an HP user's site, but that's about it. I know this is a longshot, but would anyone happen to know of a scanned manual for this beast? _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
