That slot is a DRAM slot for the program memory of the coldfire microprocessor. The command station has 8MB of SDRAM on the motherboard so doesn't need a DRAM slot. I believe that non-turbo P2K modules have 4MB of DRAM by default and the turbo ones have 8MB. You can put a 16MB SIMM into that slot (and the OS will recognise it). The only benefit of more memory is that at start up the micro reads all of the preset memory from the wave slots and stores the information in the DRAM. If you have ROMs with lots of presets/riffs etc you can actually run out of RAM on the non-turbo modules. You can do the same on the turbo modules but it is less likely. You can't run out of DRAM if you have 16MB with any combination of the existing ROMs

Did you guys figure out what the extra RAM/ROM slot was for?

Do your motherboards have what looks to be another ram/rom slot on the opposite end from the 4 sound roms? I noticed it on my Vintage Pro, but not my XL-7. I wonder what it is for?
