Hi, I came across your 8008/8080 web page while searching for info on old Tektronix logic analyzers. I recently bought a model 1220 analyzer on eBay which is very similar to the 1230 you describe. It didn't come with pods or probes, but I thought I might be able to improvise something. After some study of the front panel connector with an ohmmeter and voltmeter, I believe I've identified the data lines, power and ground, and some other inputs that must be used for clocks and control signals, but the analyzer doesn't respond to any of the signals I feed in. It seems to have some mechanism for recognizing that a compatible Tek pod is attached. The input channels just show up as "unused" when I attempt to acquire data. I suppose it could be some setup step I'm missing, but I don't see anything on the various menus that looks like a pod enable. I'd appreciate any insight you can give me into this problem. Also, are you aware of other pods that go with these units besides the P6444's? Thanks, Dan
