A while back, I picked up a Tektronix 1220 Logic Analyzer on eBay for something like $35 plus shipping. The catch was, it came with no probes or manual--and that's turning out to be a pretty big catch. It has two dual-row 40-pin headers for connecting the probes; and without knowing the pinouts, I don't have much hope of getting the analyzer to do anything. I searched Tek's web site for information on the 1220, but they had nothing.
I emailed Tek's tech support to ask whether they can give me any information on it, and we'll see what they say. Meanwhile, I've started transcribing some of the menu and help screens, to figure out a little more about how to use this thing if I can ever get it to work.
