    Hey Guys,

    Prototyping circuits involving many ICs on a breadboard has proved itself over and over again to be ineffective and inefficient in my projects. Extremely heavy board capacitance and inductance causes frequency shifts and signal ghosting.

    I believe I will transition to wire-wrapping. I suppose with 30 gauge wire, there will be less noise because of such small wire radius. Is this an effective method of prototyping digital circuits?

    Using 30 gauge is a pain, but wire wrap is very flexible and allows modifications. The cost of sockets is pretty steep, though. I seriously doubt that 30 ga wire will be less noisy than 26.

    You do have interesting problems with decoupling caps. So-called flea clips come in handy for spotting capacitors close to the Vcc pin.
