Looks like you have two CMOS digital IC's, two optocouplers, and two which I don't recognize off hand (although 5087 sounds familiar). The 4001 is a CMOS quad nor gate. The 4069 a hex inverter. A good reference for CMOS (although a bit dated) is the CMOS Cookbook, by Don Lancaster. You can find it at many electronics stores or mail order. In general, his books are very good at helping beginners advance quickly. The CMOS Cookbook has pinouts for most common CMOS IC's. As for the rest, many semi. companies publish cross references which give varying amts. of info on IC's and transistors, and cross reference (!!) them between manufacturer's numbers. Note: after a while, many part numbers are obvious--e.g. the 4069, whose prefix is relatively unimportant. Try going to a local electronics store and asking for a "semiconductor cross reference". Common ones are by NTE, RCA, ECG. Usually, they will give you one for free--some may charge $2-3. It's probably worth the cash to get one. Beyond that, start acquiring manufacturer's data books! Sometimes I think I spend more time doing that than building things! It can be a real challenge prying them loose for free, but you can get most databooks by calling a regional distributor for TI, Motorola, NS,etc. and asking. Sometimes it helps if you give them a business, school address, or sound like someone who will buy lots of parts. Also, companies like Active, Digi-key sell these books (at freaking outrageous prices!!) (Intel does that themselves--I avoid Intel!). It might be worth it for you to buy at least the CMOS and TTL databooks for one manufacturer. Note that the databooks for CMOS and TTL will be largely the same from all manufacturers. I think TI books are probably my personal favorite, and they are pretty good about giving them away. Well, if I had more time, I would look up the rest of those IC's, but I have to run. Control systems homework to do :( Good luck! Paul
