This helped me narrow things down. I tried various combinations until I 
looked very carefully at both the memory SIMMs and the motherboard and 
noticed a strange fuzz which looked a little bit like how circuit boards 
look when a battery has leaked and has caused corrosion. I cleaned both 
the SIMM which had it as well as the motherboard slot, looked for anything 
which might've caused it (leaky capacitor, for instance), but I couldn't 
find anything, so I put everything back and got blinky lights, then the 
tones that play after several minutes!

     5         MEM    OK
                      32MB   0A,0B,0C,0D=4MB, 1E,1F,1G,1H=4MB

Next... Does anyone know what this error means?

I'm not using the video display, but it'd be good to know since I'd like 
to use it someday... The manual seems to say something about the DAC, but 
I can't find the specific error which corresponds to this. Also, the LEDs 
show 0010 0111, which isn't even listed in the error code list for the 
LCSPX. Any ideas?

Thanks,
John
