        good - because the replacement software wont fit a 324

        this is actually built for a 1284 but it should work i think
        it expects a 20Mhz crystal
        changed config files are included for viewing

          i forgot to say,
          you need to reprogram the 8 pin microcontroller that controls power, or replace it with a small circuit

              yes,
              lots of new features.
              but the biggest thing was the circuit for power.
              the original 8pin microcontroller seemed to not go into sleep-mode sometimes and was draining the battery

                Which ESR meter would you reccomend for testing caps in vintage solid state audio gear? Do i need LCR so i can measure at different frequencys?

                  vintage and solid-state arent 2 words you often hear together.
                  you mean 70's and 80's ?
