Notes:

OFF = OPEN, ON = CLOSED
Switches 5 and 6 on a PC or XT motherboard must be set to ON.
"MultiSync" monitors at this time tended to support 15-31.5kHz (NOT 31.5 and up), and used a 9-pin digital connector.
25kHz monitor requires Jumper P8 set to connect pins 2 & 3 (not available on VIP).
Compaq Internal Monitor requires an "optional module" (no longer available).
IBM Analog monitor support is only available on the VIP
