XSIMM10 memory expansion board

XSIMM10 (Ten X-Sim) was manufactured and sold from 1994 by Systems Research Ltd., Tokyo. It is a memory expansion board for the X68000 series. This product uses commercially available SIMM modules (not included) mounted on board, and is compatible with X68000 I/O expansion slots.

XSIMM10

Selection and implementation of the SIMM module

This XSIMM (Single In-line Memory Module) board can be used with the following commercially available SIMM modules for compatible machines:

  • PC/AT: 9-bit (with parity) 30-pin
  • Macintosh: 8-bit, 30-pin

However, due to the size limitations of I/O expansion slots, there are following SIMM module vertical size restrictions:

  • When mounted in slot 1: Less than 15.3mm
  • When mounted in slot 2: Less than 20.4mm

If the size is exceeded, the adjacent slot is unusable.

In addition, when used with the following models, you must have a total of 2MB internal memory to add more RAM and 1MB of internal memory expansion board in advance.

XSIMM10 one pair of two SIMM modules must have the same access time and memory capacity per pair

XSIMM10 SIMM modules must have the same access time and memory capacity as a matched pair or two pairs. The RAM can be expanded up to 10MB maximum.

SIMM memory modules that can be used per sheet, the sheet is 4MB / images or 1MB /. However, to implement two pairs is not a 4MB SIMM modules. • A pair, each SIMM modules can be implemented 4MB / images or 1MB /. (You must specify the amount of memory on the SIMM module that implements). • B pairs: each SIMM modules can be implemented only 1MB /.

DIP switch settings S1 DIP switch settings as pictured above, there are two of S2. The configuration of the projection set at yellow. - Set to 0: projections to ON (S1, the displays and S2) that. • 1 set: OFF side protrusion (the number) to. (OFF = 1 have been displayed on the board) DIP switch settings as shown below.

DIP switch settings, etc., was taken from the instruction manual XSIMM10 Systems Research Inc., Tokyo.

* The product's manufacturer, Research Systems, Ltd., Tokyo is.
