Re: ESR meter upgrades
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

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

Re: ESR meter upgrades
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

Re: ESR meter upgrades
vintage and solid-state arent 2 words you often hear together.
you mean 70's and 80's ?
