What if you set output-device=screen
does that fix things when input-device=keyboard!
When you power cycle the LX with the keyboard plugged in, do you get the
beep when it first powers up? Do the lights flash? If not, check the
fuses on the motherboard. I think it might be possible that the serial
connection works, if forced, while the prom may not realize the keyboard is
there if it can't get power through.
If that's not it, check the rom revs on your two lx's. Perhaps the
one on your working LX is newer than the one you're trying to use, and thus
your original supposition that it doesn't like the type 3 keyboard is
correct for some versions of the prom.
