I'm trying to inplement a complex stimulus protocol. My current stimulus time can't do it. I used a Digitimer D4030 many years ago - and my recollection is that I could do protocols similar to the one I want to do. So I purchased on on EBay - but it didn't come with a manual, and I can't remember how to program the breadboard. (by "program", I mean stick the pins in the right places to make it do what I want to do).
