 XSIMM6 (Six Sim X) was invented and manufactured in 1994 by Systems Research Ltd., Tokyo. It is a memory expansion board with built-in SIMM memory socket and there are two variants of it:
   *XSIMM6 designed for X68000 XVI
-  *XSIMM6c designed for X68000 XVI Compact.
+  *XSIMM6c designed for X68000 XVI Compact
-This is due to different shape and mounting positions of internal memory expansion for XVI Compact and XVI.
+This is due to different shape and mounting positions of internal memory expansion for XVI and XVI Compact.

-These XSIMM (Single In-line Memory Module) is installed in the SIMM modules following the vertical dimension of 30 mm are commercially available.
+These XSIMM boards use the following 72pin SIMM memory modules which height must not exceed 30 mm (the default height is 25 mm).
-For compatible machines • PC / AT: 9 bit (with parity) 72 pin for Macintosh: 8-bit or 72-pin 4MB, SIMM's 8MB (70ns and there is 60ns, which is OK but, 60ns and the clock up if ones) 2MB of memory XVI by the additional 6MB or 4MB.

-Middle of the board as the left picture, the bottom of the SIMM installed, with a dip switch to set the memory in this expansion area.
+It supports 4MB and 8MB SIMM's (70ns and 60ns SIMM's will work but only at 70ns). It can expand the X68000 memory with additional 2MB, 4MB or 6MB.
-DIP switch settings, proceed as follows.
+There is a dip-switch panel in the middle of the board right below the SIMM socket.
+The dip-switch settings are as follows:

+The memory will be expanded with additional 6MB even if an 8MB SIMM will be installed and all four switches are set to ON.
