ELC RAM seems to be the same as IPX RAM; my IPX has RAM out of an ELC.

I believe you're correct about the LX; it _requires_ 33 bits, but it will
_accept_ 36 bits. I have 36-bit PC RAM in mine, and it works fine. Also,
the LX/Classic will take two 32 MB SIMMs in the first bank, and four 16 MB
SIMMs in the other two banks, for a total of 128 MB.
