Finally did a more complete reverse-engineering of Futurlec's AT90S2313 development board, since I can't seem to find a schematic or useful source code anywhere. Here's the disassembled test program, partially commented, which compiles with AVRA to an identical binary to the one pulled from my board using PonyProg2000. Now I just want to hack it down to a simple on-off switch, for now, to remotely turn on my radio. Kind of like an X10 controller. Of course I can reprogram it later to do something more useful, but lacking optoisolators, I need to have something to connect the laptop, running off the inverter, to my 12V power system. It's a no-no connecting the AC neutral to DC ground.
