">According to my IBM information (the IBM Configurator, supplied to dealers), there is a 16MB IC DRAM module (IBM # 66G5109)and also a 16MB DIMM module (84G2153). To install one or two DIMM modules also requires the DIMM memory adapter (84G2151). A maximum of 40 MB may be installed. It would appear that if you want to add more than 16 MB RAM, then the DIMM memory adapter is required, although my information is not clear as to whether IC and DIMM modules can co-exist in the same machine." That may be true if you stick with IBM memory, but you can certainly get a 32 meg DRAM card (I have one in my 755C, which I have had since just after they appeared), and it works fine. So that's the best way to go if you want 40 megs total. Now I believe, but have not been able to confirm, that there are 32 meg DIMM modules, allowing a max memory of 72 megs.
