Many Sun workstations and servers use a 13W3
connector which includes three pins called sense mode pins. These pins may be grounded in
various combinations resulting in a specific set of sense code values. The sense code
values describe the monitor to the frame buffer of the graphics card. Raritan sells a KVM box called the APSSUN which can be
used to convert a standard PC signal into the appropriate 13W3 signal and adapts the PS/2
keyboard and mouse connectors. Rose Electronics
also sell Sun converters. See our Keyboards, Floppies, Cables
and Mice page for prices. However, a simple and inexpensive adapter can be used
to achieve the same end: the Ultraspec #1395. The Ultraspec #1395 adapter reports sense
mode 6 to the Sun frame buffer and presents the Sun composite sync to the input pin on the
monitor. You can buy this adapter from UltraSpec Cables, Inc., 170 Oberlin Ave. North,
Lakewood NJ, 08701, Phone (800) 622-2537, email firstname.lastname@example.org,
