Thats not necessarily the wrong memory. My 755C uses the same memory as
the 750 series I believe. There are two options for memory on these
machines. One is an IC DRAM card which looks like a pcmcia card. The
other is DIMM modules that look like SIMMs cut in half. To use them you
need an adapter that fits in the ICDRAM slot. (you have to remove the
clear plastic insert below the Floppy for the adapter to fit by the way.
The adapter from IBM is pretty cheap (~$40). The part number on the
back of mine is 59G3998.
The advantages to the adapter are two. 1) There are two DIMM slots on
the adapter so you could buy a 16MG DIMM at one point and another later
and could use them both. You'd have to throw out the old ICDRAM card
since only one fits. 2) When I got my machine they didn't make 32MB ICDRAM
cards only 16 so the only way to get 32MB of memory was through to 16MB
DIMMs in the adapter.
I'm not sure if there are 32MB ICDRAMs that fit our machines or not. If
you asked for 32MB that might be why they sent you the DIMMs (because that
might be the only way you can get that much memory). BUT they should have
sent the adapter.
