Heathkit ID-5001 weatherstation

Does anyone on the list have any docs on the Heathkit ID-5001 weatherstation? I'm especially interested in schematics for the PSU board (I have no backlight, and one of the transistors gets _really_ hot), and the RS-232 command set. I've been googling for a while, and I've found a couple of interesting sites (like the one that sells aftermarket temp sensors to substitute for the LM3911 that the station comes with), but no abundant source of info.
