There is no way to plug a Macintosh II SIMM into a LaserWriter IINTX, or
vice versa. The two SIMMs are incompatible both physically and electrically.
The LaserWriter IINTX SIMM is .25" longer than a Macintosh II SIMM.
The LaserWriter IINTX SIMM has 128 contacts on the module, in four groups
of 32 (64 on each side).
The Macintosh II SIMM has 60 contacts, 30 on each side of the module.
