That's crazy! The PLCC 32pin connector doesn't have a standard pin
layout? Wow; that's really silly.

I see now on the datasheets. Pins 1(A18), 2(A16) & 30(A17) can be NC on
the 256KB chip. Makes sense. Seems like this chip should work to me;
just thought I would ask. I don't understand the memory layout &
behavior of the pc bios enough yet to know if this should or shouldn't
work yet.
